We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light.
Plato

Fear can be good when you're walking past an alley at night or when you need to check the locks on your doors before you go to bed, but it's not good when you have a goal and you're fearful of obstacles. We often get trapped by our fears, but anyone who has had success has failed before.
Queen Latifah

Thinking will not overcome fear but action will.
W. Clement Stone

This is all you have. This is not a dry run. This is your life. If you want to fritter it away with your fears, then you will fritter it away, but you won't get it back later.
Laura Schlessinger
