You never know what motivates you.

What you do today can improve all your tomorrows.

If you think you can do it, you can.

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

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

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

To know oneself, one should assert oneself.

The dog that trots about finds a bone.

If you're going through hell, keep going.
