Why Bother?

I want to study art or writing, whichever is available, but instead I'm stuck calculating money. I don't like it, so why bother? I'm planning on getting a job and pay for classes in the process... I'm not really sure if I could do that though... I'm guessing I might flunk a few subjects this semester, I don't have the heart to work hard for a good grade anymore. It's just that I don't want to be computing numbers for the rest of my life. I need creativity! So why bother?
