Yeah, I do believe there someone who has no hobby, I used to have a period like this, when a goal i achieved, you would feel happy in the moment but deep empty would strike subsequently, cause you don't know how to spend the rest time that you used to take it for work. But hobbies can be cultured, by insisting the things that you thought you would gradually get into it, you would finally be into it. I tried, it really works! :)
