To know oneself, one should assert oneself.

The secret of getting ahead is getting started.

Be gentle to all and stern with yourself.

Never complain and never explain.

Quality is not an act, it is a habit.

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

Well done is better than well said.

If you think you can do it, you can.

What you do today can improve all your tomorrows.
