“ The measure of intelligence is the ability to change. ”

“ The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking. ”

“ Yesterday I was clever, so I wanted to change the world. Today I am wise, so I am changing myself. ”

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

“ Be the change that you wish to see in the world. ”
