Fix That Shit question

I always like to know what people implement from this book, and what it changes for them :) Doing everything I wrote in Fix That Shit has brought my husband and I to 4 years completely fight-free now, and though I know most people won't follow my advice to the letter I've consistently heard that doing a little still helped ease their troubles.

So what piece did you take away from this and add to your life? What happened when you did? Let us know!
