Self-help ✦ Penny’s Take
Theory and Practice of Leadership
Roger Gill · 2006
62/100
👎 Skip It
Roger Gill's 552-page SAGE textbook offers the most comprehensive survey of leadership theory you'll find in a single volume, and reviewers in academic circles called it a tour de force. But it's misclassified as self-help, and its real home is the graduate seminar or the consultant's reference shelf — not the bedside table of a working manager looking for Monday morning takeaways. Dense, authoritative, and genuinely valuable in the right hands.
