"Don't be discouraged by a failure.
It can be a positive experience. Failure is,
in a sense, the highway to success, inasmuch
as every discovery of what is false leads us to
seek earnestly after what is true, and every
fresh experience points out some form of error
which we shall afterwards carefully avoid."
~John Keats
"The only real mistake is the one which we
learn nothing."
~John Powell
