Because that's where the money is?
I'm not sure if I even wanna study fine arts anymore because 1 in a million people who come out of art school actually end up being a successful and famous artist.
It's ok, we can be poor and happy! I'm studying art too... more specifically, fine art embroidery... people will take one look at my CV and laugh at the fact that I actually did a degree in EMBROIDERY! It's better than it sounds though, haha!
But don't worry, I think if art is what makes you happy, you'll be happy just making art even if you don't make all that much money. I'm mentally preparing myself for a future as a happy pauper.
