I used to think the same thing, but now I think that artistic skill is like any other. Some people are more natural than others, but in the end you've got to work hard to get it. I guarantee you that every one of those designers have put forth enormous amounts of effort to be proficient.

I'm learning design because I don't want to have to rely on others to be creative for me. It's a slow and laborious process, but can be fun when I look back on previous projects.

In my own path I'm far from there yet, though I know where I want to be.
