I agree that it's a good principle in general, but it's somewhat concerning in the implications for people who have bad things happen to them. If good things will happen if you think positive thoughts, then imagine the cancer patient blaming herself for her own negative thoughts. It blames the victim by somehow suggesting that he or she really wanted terrible things to happen, or they wouldn't have. It was the problem when the concept was talked about in the 70s and it still is now.
