I can, therefore I am.
Always desire to learn something useful.
To be a good loser is to learn how to win.
Be thine own palace, or the world's thy jail.
It's always too early to quit.
If you're going through hell, keep going.
Never complain and never explain.
Only the educated are free.
Wherever you are - be all there.
The dog that trots about finds a bone.
We learn more by looking for the answer to a question and not finding it than we do from learning the answer itself.
