i think the sense of accomplishment and pride you get from expressing exactly want you want through a craft or sport you are passionate about and pulling off a perfect execution...don't know exactly how to word it but that whole experience is better than sex (n/h).
example: you're a songwriter/composer and you create a song that just feels right. that moment when you feel "this is it!"
or those moments when you're playing a sport and you're in the zone where everything seems like it's in slow-motion, everything is just clicking and eventhough you're improvising plays, dribbles, etc, your execution is still flawless.everything is in sync.
or maybe you're a comedian and you have that ill set.
and i think what makes it more satisfying is the amount of work you put into it and you're at that very moment where you practiced it (whatever that "it" is) that you can pretty much do what you want with it, improvise, etc. you can masterfully express yourself through it, be creative with it, almost like you could elevate the culture with it.
