It's all matter of attitude. You could let a lot of things bother you if you wanted to But it's pretty much the same anywhere you go, you can manage.
I began to draw an invisible boundary between myself and other people. No matter who I was dealing with. I maintained a set distance, carefully monitoring the person’s attitude so that they wouldn’t get any closer. I didn’t easily swallow what other people told me. My only passions were books and music
It's a question of attitude. If you really work at something you can do it up to a point. If you really work at being happy you can do it up to a point. But anything more than that you can't. Anything more than that is luck.
