Go back a little to leap further.
It is hard to fail, but it is worse never to have tried to succeed.
Half of the failures in life come from pulling one’s horse when he is leaping.
I failed my way to success.
Our doubts are traitors, and make us lose the good we oft might win, by fearing to attempt.
Every failure brings with it the seed of an equivalent success.
Failure is blindness to the strategic element in events; success is readiness for instant action when the opportune moment arrives.
Newell D. Hillis
They fail, and they alone, who have not striven.
Thomas Bailey Aldrich
We learn wisdom from failure much more than success. We often discover what we will do, by finding out what we will not do.
