The 1% Book Shelf
Most business and tech books are 20 percent signal, 80 percent padding. The 1% Book Shelf is where I track the one or two ideas from each book that actually changed how I work — or the ones that looked promising and didn’t survive contact with real systems.
Every entry is a short review: what the book argues, what held up against thirty years of running infrastructure, what didn’t, and the single takeaway worth stealing. No summaries, no affiliate links, no five-star theatre. If a book only gives me one usable idea, that’s still a good book — and that one percent is what ends up here.
The working lens
Look for the system beneath the story.
Ideas earn their place here by being useful after the presentation ends and the real work begins.
01 Follow the consequences
02 Keep people in the system
03 Test it against reality
The working index
Ideas worth carrying into the work.
Start with the lead essay. Then follow whichever question feels most useful now.
