Only one person knows how it works, and they’re out today.
Knowledge is stuck in one place.

Changes weren’t tracked.
Everyone agreed on the plan. Months later, nothing shipped.

Why I Wrote "Wisdom for Data & Systems"
There’s something intriguing about coming across words written hundreds (sometimes thousands) of years ago and realizing their still applicable today.
Most of my work (career) has been around data, technology, and systems, I would read a quote about truth and immediately think about data quality (integrity). I’d come across an observation about measurement and somehow connect it to analytics. The original writers certainly weren’t thinking about databases, dashboards, or information systems, but the connection was there.
I began collecting these quotes (ideas), making notes, and thinking about them through the lens of my own experiences. Eventually, I ended up thinking “this is a book!”, and here it is.
