There are only 2 qualities in the world: efficiency and inefficiency, and only 2 sorts of people: the efficient and the inefficient.

The people who get on in this world are the people who get up and look for the circumstances they want and if they can't find them, make them.

You'll never have a quiet world till you knock the patriotism out of the human race.
