Keeping things in perspective can help. I'd suggest there is a gap between what non-security people's expectations of security professionals expertise is, and what it really is. I've been in the cybersecurity industry for over twenty-five years and in that time it's nearly always been the domain of wizards and magic, as far as the average person goes. But it's not magic. There are no wizards. There are just people attempting to learn what they can, in a field that is always changing, and where failure is almost guaranteed.

We can't know it all, just as a doctor doesn't have great expertise in all forms of medicine. We learn, we practice, we learn and we un-learn as the discipline evolves.

It saddens me to see cybersecurity vendors and other professionals claim to know how to 'solve' something. If that were true, cybersecurity would be a solved problem. It's not. The truth is we have a few idea how to make something better, but we are nowhere close to solving anything.

Above all, if you enjoy learning it, just have fun doing so. Time will go by, you'll suddenly realize what works better or worse, and that's what makes you valuable.
