I do believe I'm better than the vast majority of people, and my experiences have tended to reinforce it.
What you're seeing with my work is related but not the same. For as long as I can remember, I've been an artist. There was never a point where I thought I would do something other with my life than art and writing. I'm obviously not perfect, but when I was little, I was better enough than the people around me that I was constantly told how good it was. Because they were untrained in art themselves, they saw it as better than it actually was, and told me so. I won most competitions that I entered, to the point where (when I was 13) I started refusing to enter at all. By the time I was 17, I was well aware of how little raw skill actually mattered, beyond a certain level that most contestants had already reached, and so how it depended instead on the personal taste, mood, and philosophy of each judge. I decided the whole thing was pointless. I went to a fairly prestigious art college on a full-tuition scholarship that didn't officially exist - but when I had walked in on campus tour day and showed my portfolio and told the admissions counsellors that I couldn't afford to go with their existing scholarships, they pulled strings for me.
So I've got past experience against which the opinions of a few people on a website don't sway the balance at all.
