Quality is not an act, it is a habit.
Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
Never complain and never explain.
Know or listen to those who know.
Begin to be now what you will be hereafter.
To know oneself, one should assert oneself.
Always desire to learn something useful.
If you think you can do it, you can.
The wise does at once what the fool does at last.
My talent is such that no undertaking, however vast in size... has ever surpassed my courage.
