A great book for shy people like me, and very useful. Parts of it are skimmable, because they aren't relevant to me (anymore/yet), but other parts could bear some re-reading to keep stuff fresh in your mind when you approach new people. I particularly liked the section on small talk. I know I don't ask questions, and apparently that's the thing to do -- and it really works!
I just tried it out the first day of university with a girl I'm sort of familiar with from a previous class, though we never talked for more than a minute before. Seeing that we just had a Christmas break, that was an obvious topic to start with ("How was your break?") and we talked about that. Then we moved on to other topics common to us, such as discussing this class, the teacher, the book ("Where did you get it?" because I was looking online for it and didn't find it). Success!
I think I need to buy a copy. It's not very expensive...
