Your reaction is a somewhat natural push back against the prevalent idea of selling people on things they don't yet have.

But you probably need to temper your reaction. Surely you would expect someone to work on improving themselves. That's what education is. That's how people develop skills.

James Clear in Atomic Habits is definitely not just talking about productivity. He's talking about your health and fitness and your mental health too.

Also, why do you have become "someone else" to be a better version of yourself?

Yes, I agree with this. I think a good life is finding that balance; how much of yourself goes into production, how much into consumption. How much do your push yourself to be better, and how much do you accept and live with your flaws? How much do you invest for the future verse consume in the present? Too much either direction will lead to a bad life.
