I can, therefore I am.

Begin to be now what you will be hereafter.

Either you run the day or the day runs you.

Never complain and never explain.

Things do not happen. Things are made to happen.

To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

By failing to prepare, you are preparing to fail.
