It seems you discovered for yourself what every book on communication emphasizes -- ask questions! People would rather talk about themselves than listen to you talking about yourself, so if you just get them talking and then listen to what they have to say (you barely have to even speak most of the time!) not only will you learn quite a bit, the other person will usually come away feeling like it was a very good conversation, that you were a very good conversationalist, and will appreciate the connection with you.
