Be gentle to all and stern with yourself.

Either you run the day or the day runs you.

Know or listen to those who know.

To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

Things do not happen. Things are made to happen.

If you've got a talent, protect it.

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

Well done is better than well said.
