It's always too early to quit.

Be gentle to all and stern with yourself.

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

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

If you're going through hell, keep going.

If you've got a talent, protect it.

Never complain and never explain.

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.
