The music life. Why? What happen to all those music commitments?

Ever since I further my studies in one of the local universities, living the dorm life, I find it's hard for me to cope up with my major interest. Which is music. Especially guitar playing. I don't abandon music just like that, just that, since I start living the dorm life last semester, seems that I can't focus more on guitar anymore. Study commitments I should say. I don't study hard that much, so why? I don't know. Strange that, during the first few weekends of last semester, every time I go back home, immediately I picked up my guitar and start playing it. But, after a few weekends, gosh, the habit starts to drift away. Until now. Then, when I decide to make it a habit again, try to play the guitar as much as I can like last time, I find that, after a long no practice with my guitar, it's getting hard for me to play em. ergh. What happen to all those commitments? Sigh~ :(
