I have a confession to make, I haven't done my daily visualizing for the past 3 days. Not that I didn't want to, but for some reason I fall asleep, and the next thing I know it's morning. Bah. The sensible solution to this is to do it earlier in the evening - or maybe in the afternoon even, so even if I fall asleep I can make a second attempt.
Tony Robbins talks about conditioning the mind to do things we don't want to do in his tapes. He says that we have to associate not doing it to something really painful or bad, so as we're pushed to do it instead. Sounds good to me.
