Help!

I'm a swirl of possibilities again.

I was thinking about college majors and what I want to do, and I was just hoping someone could provide for me some insight. I thoroughly enjoy art and creating art, designing, and all of that stuff, but I simply don't know where to head with it.

I'm sort of feeling communication arts; studying graphic design or public relations?
Arts management, maybe?

I'm interested in sociology. And microeconomics. And the human psyche. And demographics.

If I were to mix all of that together in one giant melting pot - art & design, management, sociology, microeconomics, psychology and demographics - that's what I'd want to do for the rest of my life.

What does it take to become a creative director?

If I think about it hard enough, all of this is really starting to sound like advertising design. Which sucks. Because my sister is an advertising major. Is it bad to major in the same thing as a sibling?

What the fuck do I do? I know I'm the only one who can truly answer that question and decide for myself, but any guidance would be helpful.
