Since reading The Traveler's Gift by Andy Andrews which I highly recommend, I have been able to codify my life principles because they match those that he spelled out in the book.  I want to share them with you:
1/ The buck stops here: Adversity is preparation for greatness
2/  I will see wisdom: I will chose my friends with care
3/  I am a person of action: I can make a decision and make it NOW!
4/  I have a decided heart: My destiny is assured
5/  Today I will choose to be happy: I am the possessor of a grateful heart
6/  I will greet this day with a forgiving spirit: I will forgive myself
7/  I will persist without exception: I will find a way where there is no way
     You do not have to tell me anything about yourself other than what you believe in and I mean what you honestly believe in and I will tell you what you are and what you will become.  It is that simple!

Believe in yourself ONLY if you have a self worth believing in,
