Too Stupid to Quit

Teddy Roosevelt wrote...

"It is not the critic who counts. Not the man who points out how the strong man stumbled or where the doer of deeds could have done 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 and comes short again and again; who knows the 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, at least fails while daring greatly, so that his place shall never be with those timid souls who know neither victory nor defeat."

Alexander Hamilton wrote (at age 14 by the way)...

I'm no philosopher, you see, and may be justly said to build castles in the air. Yet we have seen such schemes successful when the projector is constant.

Calvin Coolidge wrote...

Press on! Nothing in the world can take the place of persistence. Talent will not: nothing is more common than unsuccessful men with talent. Genius will not: unrewarded genius is almost a proverb. Education will not: the world is full of educated derelicts. Persistence and determination alone are omnipotent.

Winston Churchill wrote...

It's not enough that we do our best; sometimes we have to do what's required.

J.D. Williams wrote...

"I've always been persistent but that's because I've always been too stupid to quit."
