I grew up thinking I should take personal responsibility for everything.
I'm not sure when this got imprinted on me, but the idea is that everything that happens around me, and to me, is my fault. Or, at least, that I should take personal responsibility for everything that happens around me. While in general, I think this is a good idea, it's gotten me intro trouble, on occasion. It leads to a very simple and visceral response to anything and everything that happens around me. Someone's reaction to me, and something I do, is entirely my fault. If someone reacts negatively to something I do, it is my fault. If someone thinks I'm stupid, or doesn't agree with a point of mine, it's because I've failed, in some way. If someone gets away with something they shouldn't, it's my fault.
Needless to say, this is a dangerous way of thinking that places a Hell of a lot of responsibility on me.
And yes, as I said, I don't think it's an entirely bad way of thinking, in that I think far too many people think *nothing* is their fault. But I'm not Atlas, and I can't hold the world on my shoulders. I can only do the best I can, and let things happen as they will.
It sounds like a simple thing, but it's something I'm learning, over time.
