There's huge opportunities to continue to improve efficiency in the way the government operates and improve the way government provides services to its citizens.

I'm very proud that our country still produces people like my son, who choose the path less traveled; that knowingly step up to serve, even though our country is tearing itself apart with things like political machinations.

I ran for Congress not because I was having a mid-life crisis. I left the private sector because I saw a looming financial crisis that was coming to this country. It's unsustainable.

I had the interesting experience of having lived and worked for six years in China with Procter & Gamble, and that just changes, I think, your whole perspective in living overseas and living in a country like China.

For me, being able to engage with the details when necessary, when there's a challenge, when there's a particularly important pivot, yes, you have to do that. But in general, a leader needs to trust their commanders, needs to trust the team they've assembled, to actually execute in the right way.

In China, you have to have a strong leader for a business to get anything done.

Women need to be in key operational roles where they run businesses in the organization. Sometimes when organizations focus on leadership diversity, they're mostly in areas like HR or non-operating line functions.

A leader who doesn't hesitate before he sends his nation into battle is not fit to be a leader.
