Be gentle to all and stern with yourself.

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.

Be thine own palace, or the world's thy jail.

If you're going through hell, keep going.

Always desire to learn something useful.

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

If you think you can do it, you can.

It's always too early to quit.
