There is no failure except in no longer trying.
I know not how to defeat others, I only know how to win over myself. The real and most dangerous opponents we face in life are fear, anger, confusion, doubt and despair. If we overcome those enemies who attack from within , we can attain a sure victory over any attack from without.
hope for the best, prepare for the worst
Even monkeys fall from trees.
A single tree doesn't make a forest.
Don’t try to eat an elephant for lunch.
