It's always too early to quit.

Be thine own palace, or the world's thy jail.

The wise does at once what the fool does at last.

If you can dream it, you can do it.

If you think you can do it, you can.

To be a good loser is to learn how to win.

By failing to prepare, you are preparing to fail.

The dog that trots about finds a bone.

Things do not happen. Things are made to happen.
