In the movie Ratatouille, Remy's motto was that anyone can draw.
I've started taking drawing as a hobby back in 2007. Naturally, one of the first things I wanted to draw was the Mona Lisa, the most famous of all artworks. I produced the image on the left and, believe it or not, I was ecstatic about the results. Basically, I thought that I did a great job. Little I knew back then that I was obviously not drawing any better than an average 6 years old child.
Fast forward to 2011, going through four years of learning about drawing only through trial and error (very inefficient), and I had improved a lot. It was still not anywhere near excellent, but the contrast of the comparison is stark. Ironically, I didn't have the same feeling of euphoria as the one I had in 2007. And that's probably because I knew better that time.
