Self-help ✦ Penny’s Take
The 21 Indispensable Qualities of a Leader
John C. Maxwell · 1999
Maxwell's character-focused companion to his Laws of Leadership book covers the inner qualities that underpin effective leadership — integrity, servanthood, generosity — with an explicit Christian values foundation that makes it especially at home in ministry and faith-based organizational settings. At 160 pages with reflection questions, it's an easy fit for small-group study. The 21-item format feels a bit arbitrary and the anecdote-heavy approach means it's motivational rather than research-grounded, but over a million readers have found it worth their time.
