If you think you can do it, you can.

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

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

Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.

Only the educated are free.

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

The secret of getting ahead is getting started.

I can, therefore I am.
