Hi, Marcel - thanks for two more powerful observations.

I would nominate the trait of Honesty as most essential for leadership success, for several reasons.

First, Honesty is required both for self-knowledge and awareness of others.  If you would truly know yourself, as you advise above, you have to be willing to be way more honest than most of us would probably choose to be about our own motivations and actions.

Second, Honesty generally improves all leadership behavior and thought, when mixed with compassion and emotional intelligence.  The ability to .appraise a situation, consider alternatives, and choose an effective path forward requires that level of honesty.   Hard situations are seldom improved by any level of dishonesty, whether as fluffy as sugarcoating bad news or as devastating as intentionally withholding or actively revising really bad news.

Thanks for both parts of this series ... much to consider and appreciate:)

John
