Quality is not an act, it is a habit.

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

I can, therefore I am.

What you do today can improve all your tomorrows.

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

Leap, and the net will appear.

If you're going through hell, keep going.

Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.
