Be gentle to all and stern with yourself.

Know or listen to those who know.

To know oneself, one should assert oneself.

Well done is better than well said.

Wherever you are - be all there.

What you do today can improve all your tomorrows.

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

Quality is not an act, it is a habit.

If you think you can do it, you can.
