Image matters
Unless you're a very outgoing person or working in marketing, you will probably not want to boast about your achievements, or maybe not even see what you do as worth mentioning at all. In fact, you might hate the idea that everyone expects that you constantly post photos and write updates about every little thing that happens in your life. I can see where you're coming from, and there is nothing wrong with that, but if you're a game designer, publisher or a press person, you will need to try and be somehow present, even if that feels alien.
