If this is a blessing, it is certainly very well disguised.

Courage is the first of the human qualities because it is the quality which guarantees all the others. Without courage, all other virtues lose their meaning.

A man is about as big as the things that make him angry.

Men stumble over the truth from time to time but most pick themselves up and hurry off as if nothing happened.

The empires of the future are the empires of the mind.

Continuous effort--not strength or intelligence--is the key to unlocking our potential.

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

We shall draw from the heart of suffering itself the means of inspiration and survival.

I have nothing to offer but blood, toil, tears, and sweat.

We make a living by what we get, we make a life by what we give.

We shall show mercy, but we shall not ask for it.

We shall neither fail nor falter; we shall not weaken or tire...
Give us the tools and we will finish the job.

Never give in, never give in, never, never, never, never--in nothing, great or small, large or petty--never give in except to convictions of honor and good sense.

For myself, I am an optimist--it does not seem to be much use being anything else.

It is always wise to look ahead, but difficult to look farther than you can see.

The maxim "Nothing but perfection" may be spelled "Paralysis."

An optimist sees an opportunity in every calamity; a pessimist sees a calamity in every opportunity.

Success is going from failure to failure without losing your enthusiasm.

One ought never to turn one's back on a threatened danger and try to run away from it. If you do that, you will double the danger. But if you meet it promptly and without flinching, you will reduce the danger by half. Never run away from anything. Never!

Courage is what it takes to stand up and speak; courage is also what it takes to sit down and listen.

It is no use saying "we are doing our best." You have got to succeed in doing what is necessary.

What is the use of living if it be not to strive for noble causes and to make this muddled world a better place for those who will live in it after we are gone.
