Dude, life is about choices. If you want to sneak out of the house and hang out with friends till the sun comes up, then I say do it. This is the biggest joke that will be ever played on you:

We're studying all day to be pushed into the 'real world'...

The real world is indifferent to your school-aged 'accomplishments'. I barely graduated public high school (while disobeying as many directives from my supposed superiors as I possibly could--sometimes just for the fun of it), and I have an awesome life now at age 31. I literally couldn't ask for anything more than I have. And I did it all on my own terms.

The founder of this site, mk, has a saying (and it's the main philosophy of Hubski in general), "Each of us helps to create the world we live in." (Or something similar.) Fuck the world you're given; make it up as you go. Or, as Cat Stevens wrote, "If you want to sing out, sing out, and if you want to be free, be free." The internet can be informative, engaging, educational, and many other good things, but it's not fucking freedom. Don't confuse the them. Live, son. That's good advice.
