The Thinking Behind the Tweet
That's a Spirited Leaders' definition. Some say Ego is a flaw. For example, if I understand him accurately, Eckhart Tolle considers Ego to be a pain body that really provides no benefit. [And I have a great deal of respect for Eckhart Tolle.] I think Ego is a valuable piece of the human condition but it is only valuable when people self-monitor and self-regulate to make sure Ego stays within boundaries of moderation.
