If you think you can do it, you can.

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

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

Never complain and never explain.

Always desire to learn something useful.

Things do not happen. Things are made to happen.

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

To know oneself, one should assert oneself.

Well done is better than well said.
