Be thine own palace, or the world's thy jail.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
The wise does at once what the fool does at last.
Never complain and never explain.
Either you run the day or the day runs you.
Things do not happen. Things are made to happen.
What you do today can improve all your tomorrows.
Know or listen to those who know.
Well done is better than well said.
When I was younger I probably didn't understand something basic about tact, but I think it kept faint-hearted people at arm's distance and that's not such a bad thing, because life is short and I know the kind of people I want to work with.
