Hello ! Thanks for your feedback ! I can understand what you're saying, I'm usually more like you but I feel like in today role if you don't market people just don't really care.
The goal with the 30 days method is really to take the first step and do everyday. IF you want to do woodworker, the program will tell you what you need to practice in the first 30 days to develop your skills. I know you wont be the world woodworker master in 30 days but I've been myself impress of how much we can learn a new skill by doing it every day. It also give you the discipline and habits to do it everyday which help you continue during the rest of the year with less struggle. :)
