I read that a long time ago and really liked it.. and never thought I would. He certainly had an interesting mind. Apparently he was also a very interesting personality, with some "demons" of his own.
I'm reading 50 Prosperity Classics by Tom Butler-Bowdon. I love his series--you get so much bang for the buck with those books (50 Success Classics, 50 Spirituality Classics, 50 Self-Help Classics).
