We are what we choose to think.
- Louise Hay

I met Louise Hay in the mid 1980's. I'll always remember her warm and true presence. I was teaching a class called The Onward Path at the time and using her book, You Can Heal Your Life, as the guide for the class. I had come up with the idea for the class just before her book came out. When I met Louise, I told her that I was using the book in the class. Shortly after that meeting, Hay House sent me a case of the books.

Garry Tan, a co-founder at Posterous, found a study by the American Psychological Association and posted an article with a similar title, You Are What You Think. So science is catching up.
