I agree, this is a good one. It's a bit rare to get retrospectives like this. Typically they tend to fall into one of three categories: the 'great-man' biography, which are more history lessons than anything else. The very poor and/or very unlucky people, those born into genetic diseases, addicted families, or some bad misfortune. And the middling and very unread section of otherwise perfectly normal people without much to say.
PG here bridges the gap between the 'great-man' and the middling-man. With a fair bit of luck, he manages to become wealthy, but not wanna-be-space-cadet wealthy. It's an under read area and full of very good lessons in that bridge of worlds. I'm not in that bridge, so my take-aways weren't as much. But perhaps with some luck, I'll be able to revisit this in the future for more savoring.
