Harold Sherman quite awhile ago, wrote a book entitled How to Turn Failure Into Success. In it he gives a "Code of Persistence." If you give up too easily, write this down and read it daily.

1. I will never give up so long as I know I am right.
2. I will believe that all things will work out for me if I hang on until the end.
3. I will be courageous and undismayed in the face of odds.
4. I will not permit anyone to intimidate me or deter me from my goals.
5. I will fight to overcome all physical handicaps and setbacks.
6. I will try again and again and yet again to accomplish what I desire.
7. I will take new faith and resolution from the knowledge that all successful men and women had to fight defeat and adversity.
8. I will never surrender to discouragement or despair no matter what seeming obstacles may confront me.
