sports, take forever to get good, so much training years and years all youth wasted
rockstar same thing, endless guitarr practicing, rehearsels, touring in minivans, very unhealthy lifestyle booze, cigaretts and drugs
moviestar takes forever to complete a movie, have to spend 3-4 months in bulgaria or some shithole...
mr olympia, endless amount of food, training, dieting over and over and over again...
i cant see myself doing any of that
