I really like the audio books by Tony Robbins, Jack Canfield, Brian Tracy, Jim Rohn and Robert Kiyosaki. They all have something interesting to say and know how to deliver it in a fun way. I certainly don't want to fall asleep behind the wheel

I once listened to an audio book by Richard Bandler and he used some sort of hypnosis type of thing with varying volume levels and several voices thrown together. I quickly changed to radio so I would not get into a trance while still attempting to drive a car...safely that is.
