McArdle weaves together corporate case studies of triumphs and flops, core findings of behavioral economics, and her own bad luck in losing a succession of jobs during the Great Recession. . . . To get where you want to go, McArdle sagely notes, you must first give yourself permission to suck. Seeing how this epiphany earns her a freer, failure-embracing growth mindset is like watching a flower unfold. McArdle combines a shrewd knowledge of economics and practical experience with a writing style that every so often segues into comedy monologue. . . . Americans fail a lot, she argues. . . . But good judgment comes from experience. And experience comes from bad judgment from failures. The key question is how you respond, whether you learn from failure and rebound.
