“As the deluge of information grows and choices continue to widen (there’s no way I could even attempt to cover science fiction from scratch today, for example), it’s easy to forget the benefits of acquiring this sort of (mostly) complete understanding in a field. I’m not even sure it matters which field you pick. Expertise is a posture as much as it is a volume of knowledge. Reading every single trade journal, for example, or understanding the marketing, engineering and sales of your field–there are countless ways to go deep instead of merely paying lip service to the current flavor of the moment.”
The only reason that I have any following in the trend following world is that people know I have done the heavy lifting research. They know I have done the onerous work for them. They benefit from that.
