LOVE this post!
I also focus on replacing the bad thought with a good one to help that brain entrainment/recalibration/reprogramming to move along. Self hypnosis, really.
And I love the Dr. Suess Game too, although one of my favorite quotes came from an interview - not one of his books:
“Nonsense wakes up the brain cells. And it helps develop a sense of humor, which is awfully important in this day and age. Humor has a tremendous place in this sordid world. It's more than just a matter of laughing. If you can see things out of whack, then you can see how things can be in whack.”
