Why The 80/20 Principle keeps getting recommended on podcasts

The 80/20 Principle came up with a genuine on-air endorsement 5 times across the episodes we processed. This page collects every one of those moments: who said it, what they said, and the exact point in the episode.

Richard Koch's The 80/20 Principle has five mentions on Tim Ferriss, which tracks given how much of Ferriss's own work leans on the same idea.

Guests bring it up when they're trying to explain why most of their results come from a small slice of their effort. Each mention links to the exact quote and timestamp.
