Our greatest glory is not in never falling but in rising every time we fall.

To See a World in a Grain of Sand And a Heaven in a Wild Flower, Hold Infinity in the palm of your hand And Eternity in an hour.

If you put off everything till you're sure of it, you'll never get anything done.

Waste no more time arguing about what a good man should be. Be one.

You can't build a reputation on what you are going to do.

Yesterday is gone. Tomorrow has not yet come. We have only today. Let us begin.

You'll never do a whole lot unless you're brave enough to try.

Man needs his difficulties because they are necessary to enjoy success.

We are citizens of the world. The tragedy of our times is that we do not know this.

One man with courage is a majority.

The desire to reach for the stars is ambitious. The desire to reach hearts is wise.

If you don't like the road you're walking, start paving another one.

Above all things, respect yourself.

Find out who you are and do it on purpose.

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

If you can't fly then run, if you can't run then walk, if you can't walk then crawl, but whatever you do you have to keep moving forward.

You say I started out with practically nothing, but that isn't correct. We all start with all there is, it's how we use it that makes things possible.

After all is said and done, more is said than done.

The fact that the great scientist believed in flying machines was the one thing that encouraged us to begin our studies.

When I go, God's going to have to give up his favourite chair.
