It's always too early to quit.

Be thine own palace, or the world's thy jail.

To be a good loser is to learn how to win.

Things do not happen. Things are made to happen.

I can, therefore I am.

Without hard work, nothing grows but weeds.

What you do today can improve all your tomorrows.

If you're going through hell, keep going.

Always desire to learn something useful.
