Great book about tackling worry. Plenty of useful tips within the book. One of them include the following:
Next time you worry about something try out Willis H. Carrier formula.
1. Ask yourself – What is the worst that can possibly happen if I can’t solve my problem?
2. Prepare yourself mentally to accept the worst – if necessary
3. Then calmly try to improve upon the worst – which you have already mentally agreed to accept
Also, another good advice from the book was to get busy. When you get really busy doing something you will have less time to worry about things.
