Many gems in this book. Most immediate and powerful for me was the five-more rule which urges me to do five of anything past my usual point of giving up. Keep hanging in a little longer. I use this idea daily in exercise routines and it works beautifully to move me just past the comfort/collapse zone. I'm also starting to use it more consciously in work before I let things frustrate me. It keeps me more open to options and to finding solutions. The book is full of this kind of practical, everyday advice written in a conversational and memorable style.
