Why do people be particularly interested in a particular type of activity? In other words, how did the hobby come about? I thought about this question for a long time, and one day I finally came up with an answer.
This inspiration is **in one I have read before**, a biology expert said in the popular science that the reason why people have a fixed dietary hobby is that it is determined by his intestinal flora, and his intestinal flora is formed step by step by his long-term eating habits. For example, Prezewala bacteria like sugar, while Bifidobacterium likes dietary fiber, and the intestinal bacteria compete with each other for space, if you eat sweets a lot, but rarely eat fresh vegetables, there will be more and more sugar-loving bacteria in the gut, and probiotics that like dietary fiber may starve to death. Probiotics take control of your brain and make you a very sweet tooth. I think the same is true of hobbies, when a person is often exposed to a certain activity when he is young, his brain will produce a response to this activity. Over time, every time he is exposed to this activity, his brain becomes excited, producing substances that make him happy, and if he is good at this activity, and the activity will bring him a sense of accomplishment, he will enjoy the activity more, and this activity will become his hobby.
This set of theories can well explain why some people have been exposed to programming since childhood, fall in love with it, and grow up to become an entrepreneur who produces programming software, such as Bill Gates. Some people read a lot of books since they were young, like to write essays, and when they grow up, they become writers through hard work.
These people who can develop their hobby into their own profession and can live a more decent life through this profession are lucky. Taking a hobby as a profession can greatly ignite people's enthusiasm for work, and make people feel happy to put in more effort than ordinary people, so as to achieve extraordinary success in this field.
