Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

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

I can, therefore I am.

If you can dream it, you can do it.

Things do not happen. Things are made to happen.

What you do today can improve all your tomorrows.

Without hard work, nothing grows but weeds.

If you're going through hell, keep going.
