Never complain and never explain.
The wise does at once what the fool does at last.
It's always too early to quit.
Expect problems and eat them for breakfast.
To be a good loser is to learn how to win.
If you're going through hell, keep going.
The dog that trots about finds a bone.
The most effective way to do it, is to do it.
If you think you can do it, you can.
The secret of getting ahead is getting started.
There are only two lasting bequests we can hope to give our children. One of these is roots, the other, wings.
