It's always too early to quit.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
After a storm comes a calm.
The wise does at once what the fool does at last.
If you think you can do it, you can.
Always desire to learn something useful.
Who seeks shall find.
Problems are not stop signs, they are guidelines.
Expect problems and eat them for breakfast.
If we would have new knowledge, we must get a whole world of new questions.
