Depends what you mean by "friend", midear. Someone to have a laugh with, or someone you can really trust, rely on, and care for. People can advise you on how to get the first, but the latter... they're harder to come by and the relationships tend to grow organically. You can be told how to meet people, to get the opportunity for friendship - but not how to make a true friend. That's something there isn't really a "guide" for - it's down to you to form that relationship. Not using and manipulating them would be a good starting point, though, yo.
