Alone we can do so little; together we can do so much.

Truth is like the sun. You can shut it out for a time, but it ain't goin' away.

We are all in the gutter, but some of us are looking at the stars.

Every problem has in it the seeds of its own solution. If you don't have any problems, you don't get any seeds.

We could all take a lesson from crayons: some are sharp, some are beautiful, some have weird names, and all are different colors, but they still learn to live in the same box...

Motivation is what gets you started. Habit is what keeps you going.

Courage isn't having the strength to go on - it is going on when you don't have strength.

Life is like riding a bicycle. To keep your balance, you must keep moving.

Only in the darkness, you are able to see the stars.

We should not give up and we should not allow the problem to defeat us.

You are never too old to become younger!

If you are humble nothing will touch you, neither praise nor disgrace, because you know what you are.

If I find 10,000 ways something won't work, I haven't failed. I am not discouraged, because every wrong attempt discarded is another step forward.

I am the captain of my soul.

My mission in life is not merely to survive, but to thrive; and to do so with some passion, some compassion, some humor, and some style

Never trust the advice of a man in difficulties.

Isn't it astonishing that all these secrets have been preserved for so many years just so we could discover them!

It's not what you look at that matters, it's what you see.

Stand up to your obstacles and do something about them. You will find that they haven't half the strength you think they have.

I believe that if you show people the problems and you show them the solutions they will be moved to act.

This is one small step for a man, one giant leap for mankind.
