Know or listen to those who know.
Quality is not an act, it is a habit.
If you think you can do it, you can.
The most effective way to do it, is to do it.
Go for it now. The future is promised to no one.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
Problems are not stop signs, they are guidelines.
To be a good loser is to learn how to win.
If you're going through hell, keep going.
If we would have new knowledge, we must get a whole world of new questions.
