Ambition should be made of sterner stuff.
Hitch your wagon to a star.
You can't hold a person down without staying down with him.
That must be wonderful; I have no idea what it means.
I fear explanations explanatory of things explained.
Those who write clearly have readers; those who write obscurely have commentators.
Not failure, but low aim, is crime.
In great attempts it is glorious even to fail.
Aim at the sun, and you may not reach it; but your arrow will fly far higher than if aimed at an object on a level with yourself.
You can easily play a joke on a person who likes to argue: agree with him.
