Without hard work, nothing grows but weeds.

I can, therefore I am.

Be gentle to all and stern with yourself.

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

The most effective way to do it, is to do it.

It's always too early to quit.

If you've got a talent, protect it.

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

Expect problems and eat them for breakfast.
