Never complain and never explain.
Either you run the day or the day runs you.
It's always too early to quit.
Well done is better than well said.
Be gentle to all and stern with yourself.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
Begin to be now what you will be hereafter.
The secret of getting ahead is getting started.
What you do today can improve all your tomorrows.
A sense of humor is the ability to understand a joke - and that the joke is oneself.
