I can, therefore I am.

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

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

Who seeks shall find.

What you do today can improve all your tomorrows.

You never know what motivates you.

By failing to prepare, you are preparing to fail.

If you're going through hell, keep going.

Go for it now. The future is promised to no one.
