Coincidentally, my own search for patterns in history and my way of dealing with tactical decisions has had a similar effect on how I see and do things—e.g., I now view the last 500 years as recent history, the most relevant historical arcs seem about 100-plus years long, and the patterns I’ve gleaned from this perspective help me anticipate how events are likely to transpire, and how I should be positioned for them over the coming weeks, months, and years.
