What you do today can improve all your tomorrows.
Never complain and never explain.
Be kind whenever possible. It is always possible.
Leap, and the net will appear.
Be gentle to all and stern with yourself.
If you're going through hell, keep going.
Who seeks shall find.
Things do not happen. Things are made to happen.
It's always too early to quit.
Well done is better than well said.
A man always has two reasons for doing anything: a good reason and the real reason.
Go as far as you can see when you get there, you'll be able to see farther.
