What's more important…  getting to connected with people you have met before, or finding new people to connect with?  That becomes the challenge at every networking opportunity.  There is no right answer, and no one winning formula to success.  You have to realize that any time you walk into a room you may be pulled in two different directions.  Before you walk into a room…  try to have some goals you want to achieve, but be flexible enough to evolve with the flow of any given meeting!
