Know or listen to those who know.

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

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

Be kind whenever possible. It is always possible.

Well done is better than well said.

If you've got a talent, protect it.

The most effective way to do it, is to do it.

If you're going through hell, keep going.
