Be gentle to all and stern with yourself.

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

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

Without hard work, nothing grows but weeds.

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

By failing to prepare, you are preparing to fail.

It's always too early to quit.

Things do not happen. Things are made to happen.

Always desire to learn something useful.
