Never write for anyone but yourself. If you do so the words won’t be heart-felt or interesting; they’ll be staid and contorted. Write because you can’t not write.
Never play for anyone but yourself. If you do so the games won’t be fun or engaging; they’ll be dull and ineffectual. Play because the games engross you.
Never dance for anyone but yourself. If you do so the moves won’t be genuine or rhytmic; they’ll be flailing and empty. Dance because you’re moved to dance.
Never live for anyone but yourself.
