WOW, epic post! I can soooo relate. Will be checking that book out of the library!
I think PN has a fantastic point by making you change tiny things slowly, a big part of my problem is that I want to change it all. But as I look back over all the diets and plans that I have encountered, most of them have left me with one new positive habit. Trying to change too much at once in the end doesn't allow me to keep all of the change.
love the idea to take a risk every day. I may have to buy the book so DS can read it. He is mazimally risk averse! Congrats on your push through your fears.
You can do this!
