I can, therefore I am.

What you do today can improve all your tomorrows.

The wise does at once what the fool does at last.

If you think you can do it, you can.

It's always too early to quit.

Without hard work, nothing grows but weeds.

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

Know or listen to those who know.

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