Be kind whenever possible. It is always possible.

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

Know or listen to those who know.

If you're going through hell, keep going.

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

Leap, and the net will appear.

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.

Always desire to learn something useful.
