what to do

I know I don't want to be sitting here in this office, looking out the window on a wet, cloudy and cool day. I went over to the mall and browsed through some art books. One part of me says, " I can be a full time artist" and then I don't know if I have the energy. The need to maintain a lifestyle I've grown accustomed too is the biggest barrier. I could probably figure out how to build a business with enough income to feel like I'm putting in my fair share of household income...but then why don't I do it? Motivation? Desire? I hate what I'm doing career-wise right now.
