I think this should be the motto for entrepreneurs and those involved in startups...

It is not the critic who counts,
nor the man who points out how the strong man stumbled,
or where the doer of deeds could have done them better.
I think this should be the motto for entrepreneurs...
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 and comes short again and again;
who knows great enthusiasms, 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 timid souls
who know neither victory nor defeat.

Theodore Roosevelt
