Leap, and the net will appear.

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

It's always too early to quit.

Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

Well done is better than well said.

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

Things do not happen. Things are made to happen.

Expect problems and eat them for breakfast.
