Today I will do what others won't, so tomorrow I can do what others can't.

The future depends on what you do today.

People won't have time for you if you are always angry or complaining.

What one does is what counts. Not what one had the intention of doing.

Good actions give strength to ourselves and inspire good actions in others.

I have been impressed with the urgency of doing. Knowing is not enough, we must apply. Being willing is not enough, we must do.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

Do what you can, with what you have, where you are.

The man who does not read has no advantage over the man who cannot read.
