Is being the smartest person in the room getting in the way of your growth as a leader?

I can remember back to the first business I ran: I was new to a leadership role and everyday I realized how much more I didn't know about people and how to lead. One of my key learnings was a few techniques that actually helped give me the freedom and flexibility to focus on my strengths.

It started one day when I realized that almost every customer service decision in the business had to flow through me in some way.
