Great course that gives you everything you need to do the work and get your business off the ground …everything except doing the work for you of course! Ross shows passion in his work which keeps it interesting and gives plenty of good examples to illustrate the lesson and make it relevant. Recommended.

I like the fact that this course is dealing with the mind and body performance in order to achieve better results in life in general. It all starts with us. It gave me insights to point out my limiting beliefs which are my main problem in creating my optimal life.

I've not completed the first iteration of MasteryOS and already found it life changing. Mastering myself, taking control of my life and not constantly questioning myself and spinning out of control has been a goal I've worked on for years and never achieved. MasteryOS provides the clear and concise path to achieve my goal. Thanks Ross!

MasteryOS has opened my eyes to a plethora of information, advice, tools & tips that other courses had only scratched the surface on. The detailed & robust guidance from Ross is fantastic, and I'd highly recommend to anybody wishing to level up their life & current situations.

MasteryOS has completely transformed my life. As an entrepreneur, I was constantly struggling with bad habits and distractions that kept me from reaching my full potential. This course provided me with practical strategies to cut out cheap dopamine and focus on what truly matters. The best thing about MasteryOS is its holistic approach to peak performance—it doesn’t just address one aspect of life but helps you improve overall. Working with this program has been a game-changer, and I’ve seen incredible results both personally and professionally. I highly recommend MasteryOS to anyone looking to take their performance to the next level.

MasteryOS was exactly what I needed at this time in my life. With so many different courses and coaches in the personal development environment, it is really easy to become overwhelmed with all of the complicated approaches to self mastery, but Ross's simplicity and clarity made me actually WANT to engage with his course and complete the work. He has removed the barriers and made the work "doable".

The thing that it helped me the most with was self limiting beliefs. The strategy is so simple, but so effective to break self limiting beliefs.

Telanna Jeffers
I'm always looking for ways to improve the quality of my life and Mastery OS has added to my strategy. This course is in-depth, but not overwhelming and easy to implement. Two areas that helped me the most was reframing my thoughts around competition and also the Magic of 90 mins.

Florian
Hi! I'm Florian, a 21 year old German guy trying to balance the (really) old family business and my sports (currently) ecommerce brand. MasteryOS, even if I'm not quite though yet, has already helped me quite a bit in creating better structure in my work and getting things done. And to be honest, Ross's newsletter emails (the ones I do get to read, because they can be very long sometimes) are always very helpful as well especially for being completely free! So if you aren't quite ready to take the big step into investing money into yourself, starting with reading his newsletter can be good as well.

My name is David, I loved the course, and we all have been lost and sometimes we need guidance to find our purpose again or for the first time. I love the actions suggested to do after each lesson. That helps you to get started and build the momentum. The best thing is you build up habits to help you overcome procrastination and skyrocket.

I have been following Ross for a while now on social media, and I got lots of value from his free courses. So, I knew the value for MasteryOS would be worth it. MasteryOS made me really think about the true impact I want to make on this earth. I'm only 1/3 of the way through the course, but definitely worth the investment.

Hi, my name is Katerina. I purchased MasteryOS because I want to build an online business in addition to my full-time job as a professor. To achieve this, I need to master myself. This course exceeded my expectations because it contains all the necessary bits in a concise yet complete way! I am in the process of implementing the suggestions bit by bit and I have already seen massive changes in my daily life, my satisfaction, my mood, and productivity. The best thing about working with Ross is that you get proven concepts and no BS! Thanks for your work and mission!

MasteryOS has been a game-changer for me! The content is powerful, and the support from Ross is unmatched. It's the only course I've found that addresses self-mastery.

My name is Deborah Paul and first came across Ross on instagram. I signed up for MasteryOS as I felt I lacked clear goals and direction. This course is a powerful tool and I’m grateful for all Ross has invested into others. Potentially life-changing (but ONLY if YOU do the work!). Thanks Ross!

Michael here. I originally enrolled in the free Flow & Focus course, and I was so impressed with the quality of the material and super happy with the straight-forward no-BS manner in which it was presented, that before I finished it, I knew I was going to continue with the full MasteryOS course. One week into it as of writing this, and I have not been disappointed! Ross knows this stuff, and the course is well structured. I am super excited to see where this will take me.

Great course, really enjoyed the lessons. I think my biggest take away was 'productive procrastination'. I have definitely feel victim to this. just learning, learning, learning, but never taking action. I am excited to implement the teaching from this course and achieve my goals.

I worked with Ross during a time when I was stuck in a grueling job that I disliked. I typically entered our coaching sessions having built up stress and anxiety, and left our sessions with a sense of vigor, calm, and readiness to confront life. Ross listened to my issues and sifted out the important parts, and then gave ideas for action. Most importantly, Ross didn’t just accept my narrative and allow me to control the conversation- he dug in and opened up parts of my psyche that led me closer to the root of issues. I always looked forward to my sessions with Ross and they carried me through a difficult time.

Gary Redmond
Ross is the man! I've been working in his program for the past few months and I've made huge progress on my personal brand goals, my mindset and my productivity has gone to another level too. His advice is actionable and designed to cut through the crap out there and get you serious results in the fastest time possible. I highly recommend him and this program - you will not regret it!

Sam Waite
I bought Ross’s MasteryOS course after following him on Twitter & LinkedIn since the start of the year. I wanted to buy the course but I felt like I owed him the $150 from all the free lessons I’d already received but MasteryOS blew me away with the amount of value inside. The “Master systems” module in particular helped me cut down the amount of time & effort I was investing into my weekly tasks, meaning I could focus more on building products. The habit trackers & checklists made it easy for me to implement everything with minimal impact on my already busy schedule. Ross is a great guy, who has produced a great product. Would highly recommend.

I've been absolutely blown away by the Self-Mastery video course and community. The modules, particularly 'Master Your Mindset' and 'Master Productivity', have revolutionised the way I approach both my personal life and business. The level of expertise, authority and support provided by the Ross is unparalleled, and I wholeheartedly recommend this course to any ambitious achiever looking to truly master their mind, life and business. Cheers!

Mastery OS has helped me identify and move past the obstacles I was creating for my business. It helped me clarify my lever moving tasks and the behavior adjustments required to get me where I want to be. Ross has amazing insights on processes and productivity, it's been a game-changer for how I approach my work and planning.

Matt Head
As a new solopreneur and dad, I was constantly left feeling burned out, overwhelmed and falling behind on my goals. Productivity and systems were a challenge for me, but Ross has helped me take responsibility for my situation and level up my content game through a relentless focus on mastery across all the relevant domains. I highly recommend Ross and his programs - sign up and become unstoppable!

Nicholas Jones
Originally I started with Ross to grow my personal brand, but soon realised how much expertise he has in all facets of life. My self discipline is now on another level and has allowed to pursue my business goals and boxing aspirations. You will never come across a more comprehensive program than this one. Not only will you get a superior course but you will also work with someone who once was in your shoes and not some online “guru”.
Apr 20, 2023
Stephen Timoney
There is little Ross doesn't know about Self-Mastery. He has poured all that knowledge into this program. Struggling with your mindset he's got you covered. Not sure how to create systems to be more productive, he's got you covered. To master life you have to master yourself and this program will help you do that.
Apr 21, 2023
Bryan Lim
I’ve been following Ross on Twitter for a while now. His content has always been super insightful and helpful on a daily basis. When he announced his Mastery OS course I definitely had to check it out. I loved the Mastering Productivity and Mastering Systems modules as a productivity and systems nerd myself. So useful. The course itself is jam packed with 6 modules of content and is really well structured for both beginners as well as advanced people deeper into their journey. PLUS there is so much bonus material too! As much as the core content which made the decision to invest in myself a no brainer.

Michelle P
As a female in her 40s I'm probably as far away from Ross's target demographic as you can get, but the fact that everything he said hit home with me shows just how universal the concepts are (and what a great teacher he is!) I'm the kind of person who wants no fluff, give it to me straight advice and that's exactly what you get with Ross. He's not messing when he tells you you can master your mind by the end of this. If you truly follow the steps, you'll come out a much stronger and resilient person.

AJ Morisma
My name is AJ. I discovered Ross Harkness around the time I knew I'd ruin my life if I didn't change things up. MasteryOS helped me pinpoint the habits I need to implement (and therefore replace my old ones) to become someone driven by purpose instead of slaving away to distractions. Obviously I cant write everything here, but it would be a shame not to at least giving MasteryOS a chance. Biohacking is something you need to learn about so that you are making your biology work for you and not against you. Understanding your own biology and psychology are key steps to conquering them.

Yoo! I'm Owz, I create content on Twitter and I'm an aspiring performance consultant. I've found crafting my competition to be the highlight of MasteryOS so far. It's been a game changer. My whole life I've tried to compete with other people, and recently with people who are way ahead of me. So learning to compete with my ideal version is super helpful. I'm pumped to keep making progress with the course.

Mats MasteryOS removes guesswork and provides a straight line towards self mastery focusing on fundamentals. The best thing about MasteryOS is that it's not wasting your time with filler content.

What I love about Ross is his immense value per word rate! There is no fluff, no BS, no need to increase to 2x speed to get to the good bits. It's just pure, actionable value-adding guidance distilled from the best information available out there

This course gave me clarity about what really matters in life and what areas I should focus on. Especially the areas of productivity and planning were still bottlenecks for me, which I was able to improve with the help of the course. Ross even created a document with workflows for planning the year, quarter, month, week and day at my request, which helped a lot. I deducted 1 star because it wasn't specific enough for me in some places, although I am also someone who needs it to be very specific.

After struggling to grow my personal brand, and struggling to grow personally, the best decision I made was to work with Ross. He has completely changed the trajectory of not only my business, but also my habits and how I show up for myself on a regular basis. He’s a no BS, straight to the point kind of guy, and that’s exactly what I was looking for. If you’re looking to level up in any area of your life, I’d highly recommend working with Ross and to take advantage of his mentorship.

Ross's MasteryOS course is life changing. He provides information on mindset rewiring and more, which you don't see anywhere else.

MasteryOS has been life-changing for me. It is the only holistic course that covers EVERYTHING you need to know and do in order to get your life together. I've bought this course in July 2023 and to be honest, it's the best investment I've made in myself so far. I'd like to add that I'm usually REALLY skeptical about these kind of courses, and I followed Ross on Instagram for half a year until I decided he was legit, another four months until I signed up for his freebies and ANOTHER two months until I bought his course. And what can I say? It's been worth every penny, and much more than that. For the longest time I've been feeling a little discontent with my 9-5 (which was still a good job at the end of the day) - I knew I needed more from life, and I knew I didn't wanna make hardly 2k a month after taxes for the rest of my career. And with MasteryOS, I finally found my purpose that I didn't even know I was missing before I stumbled across Ross. Ross has a very down-to-earth-no-bullshit way, which I really appreciate, and it was the kick in the but I needed. If you're doubting if this is worth your money: It is. It SO is.
