All good thoughts and ideas mean nothing without action.

How little can we foresee the consequences either of wise or unwise action, of virtue or of malice. Without this measureless and perpetual uncertainty, the drama of human life would be destroyed.

I never worry about action, but only about inaction.

Life consists in penetrating the unknown, and fashioning our actions in accord with the new knowledge thus acquired.

Out of anger comes controversy, out of controversy comes conversation, out of conversation comes action.

I don't do things for the response or for the controversy. I just live my life.
