But if we break away from all our 'cliques and groups', won't things get a little lonely? The human being is a social animal after all, even if we don't always feel that way. Being too relentlessly individual can make a person very selfish, and if you think about it, to make sure that you were being suitably individual all the time you'd have to be constantly checking to make sure you weren't doing the same thing as someone else at every moment in your life. That could get a little exhausting...
I guess what I'm trying to say is: it's possible to worry overmuch about whether or not one is sufficiently individual and inspired. No matter how many groups you belong to or how generic your outfit and the contents of your lunchbox are, nothing can take away from the uniqueness of your thoughts, feelings and base pair sequence. This applies to everyone, hence, everyone in the world is an individual! =D
By the way, there's heaps of innovative art and music out there of you're prepared to dig a little for it - and it's worth remebering that just because something is mainstream doesn't mean it's bad - in fact, it's probably popular for a reason, even if that reason isn't necessarily a good one in one's own opinion =)
I can, however, understand the feelings that prompt the rant - homogeneity can begin to seem overly prevalent sometimes. Take heart - it's an illusion! =)
