I was watching an old Alan Titchmarsh "Love Your Garden" episode yesterday. They were doing a garden makeover for a wonderful 93 year old man. He had been imprisoned by the Japanese for nearly four years, and worked on the infamous 'death railway.'
He had suffered the most inhumane treatment, and seen the most dreadful things. Only his indomitable spirit kept him going. After the war he met the love of his life, but had lost her after 68 years of marriage. He was a wonderful painter, but could no longer access his little studio in his unkempt garden.
When asked what had kept him going through his miserable years of imprisonment, starvation and ill-treatment he said that he had tried to put the bad things to the back of his mind, and concentrate on the good. "Two men looked through the bars. One saw mud, the other saw stars." was how he put it.
I tend to have that attitude to life. My mother was always a worrier, seeing problems before they even arrived. I have a more optimistic nature. Even when the doctor found a lump in my side, a while ago, it never even occurred to me that it might be cancer (it wasn't) I just went along to the hospital expecting it to be nothing to worry about, and it was quickly sorted out.
I don't know if it's possible to change your nature. Whether you are born with certain attitudes to life, or develop them as you go along. I'm happy to be a "cockeyed optimist," as the old song says.
