The only way a man can remain consistent amid changing circumstances is to change with them while preserving the same dominating purpose.

The oldest habit in the world for resisting change is to complain that unless the remedy to the disease should be universally applied it should not be applied at all. But you must start somewhere.

To improve is to change; to be perfect is to change often.

Do you want to spend the rest of your life selling sugared water or do you want a chance to change the world?

Though things change, the future's still inside of me.

I don't know how to change the world, but I know if I keep talking about how dirty it is out here, somebody is going to clean it up.
