Hey at your previous post (I'm bi-polar and have been told by doctors that the only reason I've made it as far as I have in society is due to intelligence, which I took to mean I have it pretty severe).
And you described it pretty well. It's the destructive impulses that get you - the easiest way to describe it is that you get constantly bored, no matter what you do. So you end up doing dumb things to entertain yourself, with little to not thought as to the future and the ramifications of your actions. It's basically like desperately trying to cure boredom. It takes the right person to live with someone who is bi-polar. My mom is severely bi-polar and my dad has been with her for like 30 years now.
The cool thing about the manic phases is that people seem almost drawn to you. I don't want to see it go a lot of the time since I like the attention to a degree. For me, I keep a ton of friends around, hang out with different people daily, get updated in all of my friends lives often, etc. and I find it keeps me *close* to being entertained. Training helps, creative outlets, etc. I will say that being physically attractive is the best thing you can do for yourself if you really are crazy - and then try to tone the crazy down as you get older (and also don't do anything too stupid in your youth that you can't take back and will follow you around - I barely side-stepped those ones) and you should be fine. I have found if I find a girl really hot, I'm more likely to put up with craziness for longer. Sometimes really cool falls into that category but it's hard for most people to be crazy and still be cool.
