Basically, instead of going into a conversation or meeting nervously and thinking “how will this go?” you take different approach. You assume that you and the person(s) will establish a good connection (rapport).

How do you do that? You simply pretend that you are meeting one of your best friends. Then you start the interaction in that frame of mind instead of the nervous one.

First impressions last
So setting a good frame at the very beginning can bring more enjoyment and better results out of any kind of meeting. That’s one of the reasons why it’s so useful to smile when you first meet someone. And it’s also important to consider that the impression made and frame set may not just last during the first conversation. It may continue throughout your relationship with this new friend, classmate or co-worker.
