LONG holidays

I am having long holidays. 5 months i passed my days without doing nothing significant and there's another one month to go. Practically, I am getting lazier during this long holidays. Such a sedentary life style i am living. Hating my very own routine, at last i enrolled for my Yoga Class on May to make myself more active. I am happy about it because it can help me to shed some pounds but then I still cant control my internet addiction. I am spending long hours on internet without doing anything significant. All I do when I come online is to open facebook and a chatspace. All i do is CHAT CHAT CHAT and CHAT. Chat will be the priority, other than that i play pool or read something (it happens once in a blue moon though). I wonder how I can sit in one place for that long ( mine is a desktop pc). Thats the reason i decided to enroll for my law course on June intake which will be starting on July 9th. Coming week I got a short trip to Bali. So now I am kinda preparing for my trip but mentally i am ain't ready due to my muffin layers. This post-exam and holiday layers are still loving my body. The idea of dieting slips of my mind frequently. I dont overeat( i guess) but I dont use my energy much either. Typing doesnt requires much energy, so all my energy are stored as fats all over my body. Somehow I have to lose it. If not i have to lose most of my clothings which would be very much hurting. LOL!
