I can feel my life slowly trickling away

It's a beautiful, breezy day today. The sun is shining, the air is warm but not too hot, and I am sitting in my apartment studying for the stupid GRE. I could be doing any number of awesome things right now. I could be running, or riding my bike around town, or reading at the beach, or taking advantage of this three day weekend to see some sights, but instead I'm trying to remember how to compare fractions. Remember fractions? I seem to recall learning about them back in seventh grade or prior. For the past two weeks, I have stayed at home reading through this book. I've canceled plans with friends and avoided any type of fun because I am thinking about my future. When I begin to feel stressed about things like fractions, I calm myself by saying, "Don't worry, it's just your future." My life has somehow become a fun-suck. But even now I'm wasting precious study time. The wind is blowing and the air smells nice, like grass and trees and ocean, or at least that's what I'm imagining from my sad and fun-less desk.
