Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

If you think you can do it, you can.

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

Never complain and never explain.

I can, therefore I am.

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.
