If you think you can do it, you can.

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

It's always too early to quit.

Always desire to learn something useful.

Things do not happen. Things are made to happen.

The most effective way to do it, is to do it.

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

Who seeks shall find.

What you do today can improve all your tomorrows.
