Get the fuck out of your house and drink some beer lieutenant. If you don't you'll look back at the end of the year and go 'fuck, where did one of the best years of my life go?'. Sure, you might get a slightly better ATAR score or end up at a slightly better uni if you spend your nights lurking VCE forums, but you'll miss out on so much action. You'll miss out on alcohol and on dancing and on food and on making a complete fool of yourself and on girls and on mates. Then next year when you go out to clubs and bars you won't have any idea what drink to buy a girl or what the fk someone means when they invite you to Eurotrash (yes, I thought it was an insult too the first time... there was an awkward pause).
I'm not saying throw away all of the freakin' vce, but put it in perspective man. It matters very little in your life. Having a fun time matters a lot more. Sure as hell tone it down the days before exams, one would be foolish not to, but in the meantime you should be making as much of this year as you possibly can.
I don't mean to single you out specifically lieutenant, but there's a lot of people who are in your exact position who need to get out of a rut and have some fun.
