If you can dream it, you can do it.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

Without hard work, nothing grows but weeds.

It's always too early to quit.

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

Expect problems and eat them for breakfast.

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

Well done is better than well said.
