Title: I&#x27;ve know a number of people who were <i>really</i> good at one thing or a handful of interrelated things. That might be a programming language or specific technology, some business domain or something else, but I&#x27;ve never quite figured out how they did it.<p>I&#x27;ve tried the deep dive thing a few times and always come out frustrated. It seems like the important stuff that differentiates the expert from someone with casual knowledge isn&#x27;t documented. Sometimes it&#x27;s explained by the knowledge being locked behind a paywall or IP protection of some sort. Sometimes its not, but the knowledge seems to be locked in the brains of a few individuals or organizations and can only be unlocked if your&#x27;e lucky enough for them to take you in (employment at a company that specializes in something, or having a mentor type relationship with another expert). On the other hand, a minority of the experts I know are nearly completely self taught and I&#x27;m struggling to figure out how to manage. Generally as a hobbysit Like I said every time I&#x27;ve tried to deep dive I reach a point where I&#x27;m not sure what I&#x27;m missing, where to find it.
