It's always too early to quit.

What you do today can improve all your tomorrows.

The secret of getting ahead is getting started.

To know oneself, one should assert oneself.

If you're going through hell, keep going.

Expect problems and eat them for breakfast.

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

If you think you can do it, you can.

Be gentle to all and stern with yourself.
