Delegation is an interesting thing. Its common knowledge that to be an effective leader you have to learn to delegate, which requires you to understand the capabilities of those around you. “Are they willing, are they able?”
But delegation requires an introspective view as well. You have to understand yourself. “What can I do that no one else can do?” That’s the dichotomy: in order to delegate you must have an introspective understanding of yourself as well as an extrospective view of those around you.
