Why No One Likes Your Art

I recently read an article by Alex Mathers called "Why No One Likes Your Art: 26 reasons". It lists things like not being consistent, not having found your own style, you aren't good at it, etc etc. You can read all 26 reasons here.

Even though the article makes me sad, I really appreciated it because it rings true. It made me question whether or not I should even be selling art before I have found my true voice, and before I have reached a certain skill level. Is there no worth in the in between? Am I doing myself and my customers a disservice by selling my experimentations? Right now, art is definitely not a career. I don't make money. I earned about $1,300 last year, and $100 of it was profit. I use the money I make from each piece to fund material, classes, etc. to better my skill level and learn new things. And boy have I learned a lot in the past year.

After all, THIS was my first painting 2 years ago when I started making mixed media art and using paint.

What do you guys think about the article and selling art in general? Should artists wait until they are at a professional level (and what does that even mean? Isn't art still subjective?) or, if the artist feels happy with a piece and someone wants to purchase it, should he or she sell it?

I would love your input!
