Classic words: If you fail, at least fail daring greatly.

“It is not the critic who counts;
not the man who points out
how the strong man stumbles,
or where the doer of deeds
could have done them better.

The credit belongs to the man
who is actually in the arena,
whose face is marred by
dust and sweat and blood;
who strives valiantly;

who errs, who comes short
again and again,
because there is no effort
without error and shortcoming;
but who does actually strive
to do the deeds;

who knows great enthusiasms,
the great devotions;
who spends himself
in a worthy cause;

who at the best knows
in the end the triumph
of high achievement,
and who at the worst,
if he fails, at least fails
while daring greatly,

so that his place shall never be
with those cold and timid souls
who neither know victory
nor defeat.”

Theodore Roosevelt
Speech at the Sorbonne, Paris
April 23, 1910
