If you covet fame, if you covet all the superficial accolades, you're gonna be miserable 'cause you're never going to get enough praise. If you covet contributing something substantive to movies, music, literature, then you won't be unhappy.
My mentality is like a Samurai: They used to every day work on their technique to make themselves almost perfect. Because perfection is impossible, but every day, you get closer to perfection.
