You should also try to figure out which people are thing people and which ones are people people. Thing people enjoy hearing about new technology and other clever tools and possessions. They also enjoy discussions of processes and systems, including politics. People people enjoy only conversations that involve humans doing interesting things. They get bored in a second when the conversation turns to things. Once you know whether you are dealing with a thing person or a people person, you can craft your conversation to his or her sweet spot. It makes a big difference in how people react to you, and that in turn will make you more confident and less shy.
