[&#8230;] Irrevocable Principle by Mike Henry. Key quote: &#8220;Irrevocable principles make up our character. They define who-we-are. And character-based leaders lead and live from that “who-they-are.” People and organizations who act according to clearly stated, easily understood, congruent irrevocable principles are attractive. We grant them the opportunities to influence us.&#8221; [&#8230;]
