How comfortable are you when introducing yourself to others? One characteristic of effective Introducers is that they are naturally comfortable introducing themselves. It could also be that they have mastered the ability to diminish any short-term discomfort that arises as they do.
I believe you can build your ability to be consistent, attentive, skilled, and invested when introducing yourself. However, I think it would be presumptuous to tell you to be comfortable when introducing yourself. Whether you are an Avoider, Fumbler or just plain unconsciously competent, some of you will not be comfortable introducing yourself, no matter how many books you read.
