Next fall I am going to be in the College of Design studying Graphic Design to get my BFA (I'll still be at the University of Minnesota). To be honest, it's not even an unrealistic career path. Graphic designers are in high demand, they get paid a lot, and the job market is rapidly expanding with the increase in internet applications. It truly is my passion. The format of websites and the arrayed design of advertising is so attractive to me (I'm cool!!!!). My fervor for fonts and typography is psychotic. Layout is one of my favorite words. I've honestly been so happy since I've made the decision, even lighter. It sounds dumb but I have no other way to describe the feeling.
So maybe go out and do the thing that you've been waiting to do.
