Years ago at Defcon I met these guys who were also new to security and we figured out we had zero overlapping knowledge because they were all Java devs and I was at an MSP doing net/sysadmin. One of the guys said something I never forgot: most of the talks are ultra niche and intended for an extremely specific audience, but at a con that size, that audience can fill an entire hall. It is totally reasonable to have no idea what anything meant, and that didn't mean everyone else was just smarter than you and you're just bad at security.

I mostly have to remind myself of this when I read subreddits about hobbies / interests / skills. It's helpful to remember that the average person is extremely underrepresented because the sample size is so huge and the most dedicated people are generating most of the discourse. Makes a person feel like a talentless imposter at everything if you don't take effect into account. Can be very discouraging. I've been discouraged out of tons of interests from failing to realize that effect.
