I don't have any hobbies, I used to play games online but thats it. Maybe my problem, I don't know how to strike up a conversation with others (and maybe extend it beyond the the hellos).
Begin with just attending nearby events, and read about networking from entrepreneurs.
You could also attend courses of sales persons, they teach people exactly to begin conversation and to got what you need (sure, most sales target sale, but you could target something other, for example to get contact or to begin conversation).
