@CrowderSoup Other than the @deviantollam video mentioned above which I think is really good advice...Defcon is HUGE, and can be as overwhelming as it is exciting. The good news is that if you are somewhere, or with some people, or doing something, and you're not having a good time, there's literally no reason not to stop doing that and find something more fun to do. Don't get stuck anywhere. You will hopefully find something awesome that you really enjoy, and if and when you do, stick with that (as long as it continues to be fun) and don't worry about what else you might be missing. There's too much for one person to see anyway.
Be kind to yourself, take breaks/naps/decompression time.
