Things do not happen. Things are made to happen.
If you think you can do it, you can.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
The secret of getting ahead is getting started.
What you do today can improve all your tomorrows.
If you're going through hell, keep going.
It's always too early to quit.
Well done is better than well said.
I can, therefore I am.
After you start learning all about the mechanics of piloting a riverboat, you stop seeing all the pretty sunsets and you start thinking about the weather.
