They called him a "self-help guru," and I suppose that he was. He wrote dozens of books, with titles like Change Your Thoughts - Change Your Life, Wishes Fulfilled, and Your Erroneous Zones, which produced quite a large following. I read several of his books, always with enjoyment. His 2005 book, The Power of Intention, I found particularly interesting.
I would like to have had a personal conversation with him. I never met the man in person, but I did meet him through his books. ( That's pretty much the reason why I read books anymore: to meet the authors. ) He came across as a man with an adventurous mind, and so he could not be boring; he had learned too much to be didactic; had met too many interesting people to be pumped up with himself. He had good ideas, and a pretty good way of fitting them together.
Dr. Dyer leaves behind a large family, numerous books, several hours of presentations on youtube, and some good quotes. Here are a couple of them:
Stop acting as if life is a rehearsal. Live this day as if it were your last. The past is over and gone. The future is not guaranteed.
When you dance, your purpose is not to get to a certain place on the floor. It's to enjoy each step along the way.
