Please try to sell me something I don’t need

Each time I am invited to speak to a good size audience, I can’t help but notice the subset of individuals who are clearly there hoping they can sell to someone (if not everyone) in the room. You know who they are. They are the ones who approach the networking events like a contest to see how many business cards they can distribute and collect. It is as if someone told them that their goal is to collect as many business cards as possible and then, without permission, add those people to their email distribution list. They return to the office and proudly say “I went to the event with a stack of 60 cards, and I don’t have any left in my pocket!” What an accomplishment, right?
