I can, therefore I am.

Without hard work, nothing grows but weeds.

Expect problems and eat them for breakfast.

Be gentle to all and stern with yourself.

If you think you can do it, you can.

Things do not happen. Things are made to happen.

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

If you're going through hell, keep going.

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