Benefits of Obsession

I get obsessed with things fairly easily, it's not a bad thing, it's not a good thing either, its's just a thing. They take hold quite fast, it often only takes one exposure to set it off, sometimes I'll be aware of something for ages then suddenly it will be all my free time for the next month. They can be anything really from Helena Bonham Carter to the 3 Daft Monkeys. The obsession normally only lasts from a week to 2 months, but I will retain the high opinion that lead to it in the first place (For example, I haven't listened to a Katherine Jenkins song for well over a week, but I still believe that she is one the best singers I have ever heard).
Anyway, as the title implies I've noticed a definite change in my actions between phases where I have an obsession verses ones where I do not. Converse to what even I expected of myself, during an obsessive phase I find much easier to deal with myself and others ("easier" as we all know I'm not likely to ever find human interaction easy). I noticed this recently as I realised I felt total apathy towards everyone, even people I know matter to me. In my current phase, without obsession, I find myself more violent and argumentative than normal, angering people I want to be happy, for reasons I cannot even justify to myself.
So I've thought about why something I'd expect to make me more reclusive actually brings me closer to being a balanced and well rounded person, I have an idea but I'm sure there's no psychological basis for it all at. I think because the obsession works away in the background, I don't get as bored and therefore feel the need to create a scene through violence or provocation. Plus having something I wish to talk about can make social interaction easier (however, although I have never hid any obsession of mine, I don't always talk about them). This makes it easier for me to sit an just talk, even when the topic changes I'm ok as I've settled into the conversation.
So put simply, don't worry if you get a little obsessive, it might just stop you doing something stupid.
