Determination keeps us going when the going gets tough.

It's the squeeze we've endured that proves to the world that the final product is worth it.

Whatever you do, you need courage. Whatever course you decide upon, there is always someone to tell you that you are wrong. There are always difficulties arising that tempt you to believe your critics are right. To map out a course of action and follow it to an end requires some of the same courage that a soldier needs. Peace has its victories, but it takes brave men and women to win them.

The credit belongs to the man who is actually in the arena..who errs, who comes short again and again; but who does actually strive to do the deeds; who spends himself in a worthy cause.

The average person would have quit at the first failure. That's why there have been many average men and only one Edison.

They biggest man with the biggest ideas can be shot down by the smallest man with the smallest mind-think big anyway.

You carry on no matter what are the obstacles. You simply refuse to give up - and, when the going gets tough, you get tougher. And, you win.

There are always difficulties arising that tempt you to believe your critics are right.

Successful people reject rejection.

To strive with difficulties, and to conquer them, is the highest human felicity.

Victory will never be found by taking the path of least resistance.

And where does the power come from, to see the race to its end? From within.
