Dude, when I got to your age (I'm showing my age now) I was going clubbing and partying all of the time.... come to think of it, I didn't stop until I reached about 28...my love of Sci-fi etc was shelved for many years.
Hopefully you won't be away for years and years, but now is the time when you need to be out there, having fun in the real world, getting life experiences. You only live once my friend!!!
Its nice to know that you still pop your head round the door from time to time though!
