Amazing insight and writing! And that subheader "The routines they follow are just the tip of the Zuckerberg"- Genius!
I'm a huge advocate of personal systems because I've realized just how rewarding and effective it is to nail the routine that works for you. The problem is that most of the internet tell people what to do - the habits, per se - rather than shed light on why these things work in the first place. Or I feel like some just read about what successful people do and overlook why they do it, which as you pointed out is to develop some essential skill or trait.
Thanks for writing this! You really brought this one home.
