Happiness....? We feel happiness as a feeling, not way of thinking. Some writers saying to be an happy life, you must think in a positive way. Aristotle also said "Happiness depends on ourselves." Which is I can change way of think. Of course, I believed it was kinda assumable thinking method. Then, I read one book about happiness and it gives me a total different way of thinking. As I told you at the beginning, happiness is a feeling, we can't deny feelings by thinking negatively. Wait, before further explanation of happiness, we basically lived by eating, like other animals. Naturally we have born with feelings such as pain, happiness, sad, etc. So why we have feelings? It seems not evitable to survive. The answer is because we are social being. We feel something good and bad it's because you can feel by meeting others(animals, peoples). Now then, The book writer questioned, why we feel happiness? We are not only going to live and survive, but have sex for genration to generation. Ultimately and naturally our behaviour connected to be an attractive being. That is why we meet peoples time to time, to feel happiness. Our brain remembers when we felt happiness like meeting other peoples(When it was full of enjoy). Bad experience about meeting peoples doesn't come to happiness as well. To wrap up, we were living for social beings. Now I realize happiness exist for natural behavior. I'll keep post on more about happiness at next article. (It's not the end)
