Know or listen to those who know.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Either you run the day or the day runs you.

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

By failing to prepare, you are preparing to fail.

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

Without hard work, nothing grows but weeds.

If you've got a talent, protect it.
