To enroll or not to enroll?

Here's something else bugging me. I've been taking poetry courses at ASU for the past several semesters. I am hungry for this. I learn so much. The professors have been wonderful, each one unique and brilliant in his/her own way. But it's so damn expensive! And tuition keeps going up, up, up. This fall semester, tuition + fees for a 3-credit course is almost $2000! So, I sit here dying to take a 500-level poetry course that will be demanding and juicy, will feed my mind and spirit, and not taking the step to enroll because I think I should not be spending that much these days, with personal circumstances in a state of turnover and too much credit card debt and my inheritance dwindling as the market wallows in an apparently long-term funk. I know that's the right decision, the practical and cautious decision, but I ache to enroll, I salivate to be challenged in a classroom dedicated to poetry. Damn. I might (usually do) have a sudden last-minute change of heart and just throw money at myself! Thinking...
