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.

The happiest I ever been was when I was a struggling actor. I've had big houses and small houses. I always had work available for most of my career. When I actually had to find jobs to make money, that's when I was happy.

I was married to someone who had more money than me, but because I was the stronger earner and we lived in California - a shocking thing slapped me in the face when we divorced and I had to end up paying him my earnings.

It doesn't matter about money and fame and whatever. I really don't care about that. My thing is, I'm happy that I'm able to have kids have a hero and have someone that they can look up to.

We can have democracy in this country, or we can have great wealth concentrated in the hands of a few, but we can't have both.
