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.
