Brief but insightful - most companies cargo cultishly adopt practices without understanding the underlying motivations and reasons. That also makes it hard to apply what’s in this book - unless you can change the whole structure, it’s not going to work.

What a complicated person. Nice to see various perspectives and versions of history from different interviews. Much better than the Da Vinci bio.

Lots of interesting details about an era I’ve often glossed over. I particularly liked the account of monasteries as literature preservers despite having no direct interest in preserving literature.

I preferred Doors of Perception over Heaven and Hell. Eloquent, interesting mix of still-fresh ideas and antiquated ones.

Always nice when a sequel holds up to the first book.
