You can't be afraid of failure and you can't be afraid of success, because either one gets in the way of your work.
Don't be afraid of missing opportunities. Behind every failure is an opportunity somebody wishes they had missed.
The great question is not whether you have failed, but whether you are content with failure.
There is no loneliness greater than the loneliness of a failure. The failure is a stranger in his own house.
FAILURE, LONELINESS OF A FAILURE
