No hobbies? Too sad.
By the way, how did you find this website?
Haven´t you watched Durarara!! first?
Isn´t watching anime already kind of a hobby?
What I want to say is, you don´t need a fancy hobby which causes everyone to say "Wow, what an interesting person you are, you have such a nice hobby!", as long as you think it´s fun, it is a good hobby.
A hobby is – sorry for destroying your thread – sadly something you need to discover by yourself.
Try out different things and you´ll find what fits you most.
>>2 already gave a fine selection.
Anyways, I don´t believe you lack hobbies, I´d rather guess you might lack social connections.
Find some friends and they might share their hobbies with you.
