Impulsivity

I seem to be getting more and more impulsive.
Quitting university was a very impulsive decision.
I seem to be making decisions now, without really thinking them out at all and how they'll work out with my schedule.
Impulsivity, as I learnt at university, is related to psychopathy. Am I a psychopath because I'm impulsive? Am I becoming more psychopathic as I become more impulsive?
I'm buying things without thinking about whether or not I have enough money and even if I know I don't have enough money, I'm buying stuff anyway.
I'm committing to things without thinking but maybe previously in my life I've thought too much and a bit of impulsivity will be useful in my life.
It relates back to How I Met Your Mother again, funnily enough, Ted thinks too much, he doesn't DO, he thinks. I've always been a thinker too, never just DOING things, always over thinking everything but now I'm becoming impulsive and it's getting scary. I'm so out of my depth, I'm taking uncalculated risks and that makes my heart pound in my chest. I have NO idea what I'm getting myself into in some areas of my life and I'm scared. I'm somewhat excited but not thinking can NEVER lead to anything good. All angles must be discovered, all facts taken into account before decisions are made but right now, I'm not doing that.

Agh!
