You suck at art because of a few key reasons. First, you're lazy and lack dedication. You only want the end result, not the process it takes to get there. Second, you lack patience and the ability to learn from failure. Art requires trial and error, but you're too immature to accept criticism or mistakes. Finally, you're untalented. You can't see beauty or express yourself in any unique way, and you have no understanding of color, texture, form or composition. So, in short, you suck at art because you just don't get it. Stick to something else.
