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

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

Only put off until tomorrow what you are willing to die having left undone.

The future depends on what you do today.

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

I am always doing that which I can not do, in order that I may learn how to do it.

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

Either write something worth reading or do something worth writing.

He can who thinks he can, and he can't who thinks he can't. This is an inexorable, indisputable law.
