Ultimately, as a leader there's no one who can force you to get better except for yourself. YOU are the only person who can make YOU get better. And… a hungry person doesn’t have to tell anyone that they’re hungry - they show it by their actions.
Even before my daughter was able to talk, we still knew when she was hungry; not because she could tell us, but because her actions told us she was HUNGRY.
If you're the smartest person in the room...you might be in the wrong room. Surround yourself with people who are smarter than you, so that you can continue to grow & learn.
