I invented my life by taking for granted that everything I did not like would have an opposite, which I would like.

The crisis of today is the joke of tomorrow.

I'd rather be an optimist and a fool than a pessimist and right.

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

My heroes are the ones who survived doing it wrong, who made mistakes, but recovered from them.

You can't learn in school what the world is going to do next year.

Identify your problems but give your power and energy to solutions

Laziness is nothing more than the habit of resting before you get tired.

If you can dream it, you can do it. Always remember that this whole thing was started with a dream and a mouse.

If you enter this world knowing you are loved and you leave this world knowing the same, then everything that happens in between can be dealt with.

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

You got to get it while you can.

Make the most of yourself....for that is all there is of you.

There is a candle in your heart, ready to be kindled. There is a void in your soul, ready to be filled. You feel it, don’t you?

You can't live a perfect day until you do something for someone who will never be able to repay you.

Every problem is a gift - without problems we would not grow.

The real man smiles in trouble, gathers strength from distress, and grows brave by reflection.

Once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.

For a man who no longer has a homeland, writing becomes a place to live.

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

Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.
