Decide what kinds of new friends you want. Only you know what is important to you and what values you want your friends to have. Then try to think of the types of places that these people would go. If you are an artist, go to art gallery openings. Once you a regular at these events people will talk to you and frienships will flourish. If you're athletic consider a gym. If uncertain, try volunteering. You can volunteer at an animal shelter or soup kitchen and meet some really people. This is an especially good strategy if you are new in town.

Try meeting friends of friends, if theres any parties or anything going on always make sure you go and try making small talk, the toilets is usually a good meeting place if your wanting to make female friends!! Also try using sites such as facebook to chat to new people.
