I've spent the last six months of my life trying to finish a degree by putting on gigs for my university's media outlet. Which, juggling alongside being a self-obsessed self-deprecating run of the mill only child has been no easy task.
The biggest problem I encountered was the mind-set of students. They are bone idle and trying to convince them to do anything that isn’t sitting on their bum is a real ordeal. First year students are effectively sheep that follow their flat about in herds so if one of them decides they don’t want to do something the others follow. This was a bit of an issue because naturally it’s hard to convince a house of thirteen or so people that they should totally attend an event with bands that no-one knows about. We gave it a go by putting up posters in each individual kitchen but they sort of just thought we were breaking in to their homes. This is how they all pick up drug problems because one person says 'Hey, let's try Ketamine' and everyone else goes 'Yeah, let's try Ketamine.'
So if you're thinking of promoting gigs to students I'd suggest selling drugs, it's much more rewarding.
