Everyone knows the basic hobbies like gardening, fishing, cooking, drawing, and video games, but that doesn't say much to a person in your position. First of all, you need a good friend. Someone who would talk about anything with you, get to you know, and enjoy being around you. Hobbies these days are usually based off shows or games, and within the subject the hobby usually revolves around a character, ability, story-line, or object. To create your own hobby it's easiest done by spending your time with the subject, and thinking about it--relating to yourself. If you like it then it'll become a hobby, and what really helps is getting into the hobby with a friend. There's nothing wrong with becoming fanatic over your hobby. Fanatics usually create fan-fictions, pictures, musical remixes, and other things based off of their hobbies or enjoyed subjects. For example: I've always been a fan of the Legend of Zelda and Star Trek ever since I was a kid, and I still am.
