Lately, I’ve been reading a lot of technical books, including some of the programming language agnostic manuals that have heavily influenced my industry. It’s been illuminating, and I realize that a lot of the technical blogs I read are repeating the lessons originally printed in those books.

In as much as I read about money or business, I haven’t — but perhaps now I will.
