Be thine own palace, or the world's thy jail.
To be a good loser is to learn how to win.
Know or listen to those who know.
Always desire to learn something useful.
If you're going through hell, keep going.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
Without hard work, nothing grows but weeds.
To know oneself, one should assert oneself.
I can, therefore I am.
A good teacher must be able to put himself in the place of those who find learning hard.
