If you think you can do it, you can.

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

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

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

What you do today can improve all your tomorrows.

I can, therefore I am.

Either you run the day or the day runs you.

It's always too early to quit.

Well done is better than well said.
