It's the typical mid-life crisis kind of thing, where you just stop and wonder, 'Should I go back to university and get a law degree?'

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.
