Self-help ✦ Penny’s Take

Successful Living in a Changing World

Earl Nightingale · 2021
63/100
👎 Skip It

Earl Nightingale earned his reputation as a mid-twentieth-century voice in personal development, and his core principles — goal-setting, communication, gratitude, self-confidence — are genuinely sound. The problem is that this is a curated anthology of broadcast-era material, not original composition, and the cultural framing feels dated relative to the modern workplace. Readers who want a dose of classic motivational wisdom will find it here; readers looking for fresh frameworks should look elsewhere.
