So I don't see any reason that you couldn't have a very worthwhile purpose in that area.
As to what that specific purpose is... only you can answer that.
I get pleasure in writing a song, for instance. But even if I show it and someone likes it very much, I don't have any pleasure... I've known people who has played some of my music with his guitar during hours... but I feel nothing special because of it. I feel much better if I tell a silly joke and they laugh, for instance... and sure my purpose it's not to be a comediant... :-)
