You should livestream
This could be a long post about the motivations of people who stream and how if you stream you will become a better engineer, a more empathetic person, etc In reality I know you probably want to stream or at least are already open to the idea because you clicked on this blog post. To that end I will give you the only advice that matters.
Nothing else matters. The more you click the Go Live button the better you’ll get and the more fun it will be. You’ll start to build a community if you do it consistently and that community becomes self-reinforcing. Your equipment doesn’t matter, your choice of music or overlays doesn’t matter, just click the damn button and start doing the thing.
