For a lot of people I know, especially introverts, they would rather sit at home with a good book than walk into a room full of people they don’t know with the aim of ‘networking’. Much advice has been given about the right way to network all within a span of two hours.
None of it, unfortunately, ever really computes. Walk into a room full of people and first you will notice that people who know each other stick to the people they know.
