To know oneself, one should assert oneself.

Never complain and never explain.

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

By failing to prepare, you are preparing to fail.

Be kind whenever possible. It is always possible.

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.
