Self-help ✦ Penny’s Take
Mental Toughness
Luke Caldwell · 2019
58/100
👎 Skip It
Caldwell's six-step framework is clear and the seven-day challenge is a practical touch, but the author's credentials are undocumented, the genre is crowded with far better-researched books (Angela Duckworth's Grit, for one), and nothing here appears to offer a genuinely novel framework. Fine for a quick, motivating read but not a book to build a practice around.
