Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.

Begin to be now what you will be hereafter.

If you think you can do it, you can.

What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

Always desire to learn something useful.

You never know what motivates you.
