Success does not consist in never making mistakes but in never making the same one a second time.
We are all full of weakness and errors; let us mutually pardon each other our follies - it is the first law of nature.
It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.
The greatest mistake you can make in life is to continually be afraid you will make one.
To make mistakes is human; to stumble is commonplace; to be able to laugh at yourself is maturity.

It's always helpful to learn from your mistakes because then your mistakes seem worthwhile.
A life spent making mistakes is not only more honorable but more useful than a life spent doing nothing.
