“Things do not change; we change.”

“Nothing we do can change the past, but everything we do changes the future.”

“Things do not grow better; they remain as they are. It is we who grow better, by the changes we make in ourselves.”

“In America, we change things that need to be changed. Each generation makes its contribution to our greatness. The work that is ours to do is plainly before us; we don't need to search for it.”

“Things which do not grow and change are dead things.”

“Let us stop a while, while doing what we are doing, and begin to change what we can change…”

“We really can’t change the world. We really can’t change other people! The best we can do is to start a few thinking here and there. The best way to do this, if we are sincere, is to change ourselves!”

“If things do not change, there will be nothing left to change. Either power must pass to the people or everything will perish.”

“Simply having rules does not change the things that people want to do. You have to change incentives.”

“That which we persist in doing becomes easier to do, not that the nature of the thing has changed, but our power to do so is increased.”
