It's hard to say why we start doing something passionately during a certain period of life, while what we've loved and done before becomes boring. I've noticed that even what I've cooked for so many years with pleasure can gradually disappear from my diet, and I don't want to eat and cook it anymore. 

Human beings always need something new - like new dishes, new hobbies or new impressions. I remember that my father, who passed away quite long ago, loved different things at different times of his life. He was a hunter and a fisherman. However, in his sixties, he suddenly stopped hunting and then fishing as well. It seemed boring to him and instead he grew grapevine and did some other things. 

I've jogged for more than ten years. Yet, now I see that I need something different. Perhaps I will begin to swim in a swimming pool. Instead of playing guitar, I play piano - although it also happens less often. Does it say that I'm a fickle person? What do you think about all this?
