Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
It's always too early to quit.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
Without hard work, nothing grows but weeds.
If you can dream it, you can do it.
Never complain and never explain.
To know oneself, one should assert oneself.
Begin to be now what you will be hereafter.
