If you're going through hell, keep going.
It's always too early to quit.
Quality is not an act, it is a habit.
The secret of getting ahead is getting started.
Problems are not stop signs, they are guidelines.
Expect problems and eat them for breakfast.
To be a good loser is to learn how to win.
Be gentle to all and stern with yourself.
Never complain and never explain.
If you think you can do it, you can.
The last few years have been my happiest. I'm happy in the years that most people are blue and sad and waiting to die. I don't feel that a bit. Smiling has a lot to do with it. You can just lift your spirits by smiling a little bit.
