I've made the realisation I've lived most of it in the polarities of good/ evil, or darkness/light, almost like the squares in a chess board. Or, the parts that have been good have been very good, but the parts that have been bad have also been pretty bad (like drug-abuse and what it leads to). A problem has been that I tend to view myself from one point of view, so when I see myself from my good side it enables me to defend all the bad things I do, as the good things are real, and when I see myself for all the bad things I'v been unable to see myself outside of that. So I haven't been really integrated and tend to work with a split conscousness where I view myself from the part I'm in at the time (drugs also help enable this).
At the first part of my life the situation was pretty much that I would always do my best, and always try to do the right thing and treat people well, that was how I was raised and it worked out well at first. But with time I found that this doesn't really pay off in this world and doesn't mean you will always be treated well or that you will be rewarded for it. So when I was around 17 I started to feel like this was just too inbalanced. And I wasn't willing to live my life as a martyr, which was how I could see it turning out if I contirnued that way, and I just wouldn't do it. My sister has lived her life pretty much as a martyr, or submissive to what society and everyone else wants from her, no matter what gets thrown at her in return. But I'm not like that, I just won't stand for it too long. I don't see any reason why I should. So from that point I was more rebellious and decided I would just do whatever I wanted. I don't to anything to deliberately harm anyone, anyway, but I can do people harm without intending too and this can also be a problem (and is easier to suppress or justify).
Also, by now I don't have any problem letting people know I'm prepared to give them a hard time if they think they can get away with anything. I mean, I don't do anything silly, I just show them I'm prepared to use my intelligence against them or turn my energy against them so they don't feel so great. And then they respect you and leave you alone, which suits me fine. Although I prefer when I don't have to, but there are some shady people around. It would be nice if you could treat everyone well and they would do the same in return, but it's just not realistic, so I don't even worry about it any more.
