I had never heard of the book until I saw Gilbert on Oprah a few months ago. (She has since made a 2nd appearance)
I watched the episode on DVR and was doing chores at the same time. By the end of the show, I was riveted to the TV. I have since it watched it several times and am now halfway thru the book.
One thing she discussed on the show was how we could make a spiritual journey without leaving home. She recommended that you do three things a day:
Each morning, ask yourself what you REALLY, REALLY, REALLY want. Write it down.
Each night, ask yourself what what was your happiest moment of the day. Write it down and review it to see if patterns emerge.
Third, change your mantra. As she says, we all have one, whether we realize it or not. It is often negative, like, what an idiot I am. She suggests we change it to a positive one that helps us fulfill our potential.
I don't know if those things are in the book or not. But they seem quite compelling.
