Bill Burnett and Dave Evans apply design thinking to life itself: stop hunting for the one true calling and start prototyping, small experiments instead of big irreversible decisions. The tools that stick: Workview/Lifeview alignment, the Good Time Journal (track what puts you in flow), Odyssey Plans (draft three different 5-year futures, all of them yours), and reframing dysfunctional beliefs (“is this the right choice?” → “how can I explore both?”). Failure is data. Sequel: Designing Your Work Life.
