Never complain and never explain.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
Know or listen to those who know.
Well done is better than well said.
Be thine own palace, or the world's thy jail.
It's always too early to quit.
Expect problems and eat them for breakfast.
Problems are not stop signs, they are guidelines.
I never had the high-paying job or the company car. It took me over a decade to pay off my student loans. I never had to worry about where to dock my yacht to reduce my taxes.
