I have a Bachelor of Arts in English, which means I had a lot of formal training in reading.
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.
We all live in fear of getting blocked no matter what kind of art we're trying to do. It happens all the time, but I prefer to think of it as a bad day.
