This is a working log rather than a finished essay. As I read through the letters, I note what stands out and write down the ideas I want to explore further.

Over time, this will extend into the Berkshire Hathaway letters that follow. If it gets long enough, I’ll likely break it into separate posts by era. For now, it lives here as a single, growing record.
