Yes, while working and raising a young boy. I just needed to escape the hellish pressure of having raised millions to build a business that didn't work, and worrying about my obligations to investors and the team members I hired. It was a bunch of tiny steps that I had to slot into the constraints of a working life. I recommend "Tiny Habits": https://tinyhabits.com Fogg has good ideas about how to redesign behavior under constraints.

My guess is nope. That is very difficult to do, unless one works with people willing to make an investment to heal one of their own.

That is out there. But it is rare.
