Know or listen to those who know.

Be gentle to all and stern with yourself.

Well done is better than well said.

Be kind whenever possible. It is always possible.

Do not weep do not wax indignant. Understand.

What you do today can improve all your tomorrows.

If you've got a talent, protect it.

To know oneself, one should assert oneself.

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