“Dear friend,I feel great! I really mean it. I have to remember his for the next time I'm having a terrible week. Have you wer done that? You feel really bad, and then it goes away, and you don't know why. I try to remind myself when I feel great like this that there will be another terrible week coming someday, so I should store up as many great details as I can, so during the next terrible week, I can remember those details and believe that I'll feel great again. It doesn't work a lot, but I think it's very important to try. ”
