There is almost nothing more painful for a leader than seeing good people leave a growing organization, whether it's a priest watching a Sunday school teacher walk out the door or a CEO saying goodbye to a co-founder.

Anybody, and any company, can have a big run of success once, but if you're going to repeat that over time, you need to be aware that you need to keep learning.

I have yet to meet members of a leadership team who I thought lacked the intelligence or the domain expertise required to be successful. I've met many, however, who failed to foster organizational health. Their companies were riddled with politics, various forms of dysfunction, and general confusion about their direction and mission.

The truth is that intelligence, knowledge, and domain expertise are vastly overrated as the driving forces behind competitive advantage and sustainable success.

Mom never quit on me. My only regret is that she didn't live long enough to share some of the money and comforts my work in show business has brought me.

It has been a true honor to wear a Bloomberg badge, and this credential has been the passport to sit across from some of the greatest titans of industry, including Mike Bloomberg, the visionary behind this extraordinary company.
