I am of the mind that for some people, some adversity is brought about by their own personalities. Note the two "somes" and the lack of blame. I did not say that people are at fault for whatever adversity befalls them but that something about their mental makeup may have helped to cause some of their difficulties with the world. Once again, let me also hasten to add that I speak of the normal situations of life and not catastrophic illnesses and calamities although, even in dire circumstances such as these, the following observations might apply to a certain extent.
My mother and her brother, my uncle, serve as an example in my mind. Although they rather obviously shared similar upbringings, they had different attitudes towards the world. Neither was raised in opulence; in fact, it might be observed that both endured some deprivation. However, where Mom became suspicious and tended to see the world negatively, Uncle Charlie always seemed to be a happy, content soul.
Oddly enough, from my point of view, it was Charlie who had the greater cause to feel that he had been hard done by. He was a man who was not even five feet tall. He never married but lived with his father, until he [my grandfather] passed away. Then, he lived as a boarder in this place or that with just a room to call his own. But I never heard him complain. I think he accepted life as relatively good and fair.
While I'm not saying that Mom's life was easy, I do remember something she said in her later years that might illustrate this small point that I am trying to make. It went something like this: "David Copperfield is on TV tonight. I'd like to watch it. Both he and I have had difficult lives." She wasn't brought up in rough orphanages, and she was by then materially comfortable, and I'm sure that many humans might have readily changed lives with her, but such was her internal reality that she likened her lot to that of an orphan in Dickensian England.
As I implied at the beginning, I don't think people can help how they are programmed to experience the world, not initially at least, for I tend to believe that there is something within us that predisposes us to perceive the world as we do. I do think, however, that, as life unfolds and we become more mature and responsible, it is within our abilities to make choices about how we see the world and our lot within it. I don't suppose that it is easy for many, but I do believe that it is possible because in the end we must surely have some responsibility for the colour of the lenses that we put on to view our lives.
Blue Rodeo Rose Colored Glasses lyrics
She sees the world through rose-coloured glasses
Painted skies and graceful romances
I see a world that's tired and scared
Of living on the edge too long
