Be kind whenever possible. It is always possible.

If you think you can do it, you can.

To know oneself, one should assert oneself.

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

You never know what motivates you.

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

Always desire to learn something useful.

Know or listen to those who know.

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