There's a notion of art in this country that you have to be nutty or special or "called" in order to be an artist. I believe the questions everyone should ask themselves are, "Do you want to do it? Are you willing to do it poorly? Are you willing to do the work of doing it? Are you willing to persist when everybody tells you it's silly?" If you're willing to do that, then you can do it.
Many species of wit are quite mechanical; these are the favorites of witlings, whose fame in words scarce outlives the remembrance of their funeral ceremonies.
