Networking, the buzz word for a few years now. In fact, networking, or the action of working your network of contacts, has been around for a long time, it just changed its name: making contacts, relating to other people, interacting, helping each other...
I have an introverted personality, but I have always enjoyed interacting with other people, getting to know their life stories, anecdotes and learnings. I remember as a child I loved reading biographies because they showed me real-life examples. I thought it was great to know that these were true stories and that I could experience similar moments.
Networking for me is that, sharing life and work stories, knowing that I can do something similar, that the person in front of me has a story that can be an example for me and my story an example for them, that I can help and be helped.
