Be gentle to all and stern with yourself.
By failing to prepare, you are preparing to fail.
What you do today can improve all your tomorrows.

Who seeks shall find.
Well done is better than well said.
I can, therefore I am.
It's always too early to quit.
To know oneself, one should assert oneself.
I got up with my wife, I sat down at the computer when she went to work, and I didn't stop until she got home.
