Well if you dont look for something, you will find it... eventually, it may just take you 1 month or two months or two years... or you actually never will. On the other hand if you are social, go out a lot, talk to new people, then guess what? You will definitely meet someone sooner or later. If your too damn shy to talk to a girl on the train or at a club then be prepared to be lonely or rely on your sister to set you up with her friends, your screwed if you don't have a sister...
