I remember a judge, Judge Jeffries, who I often heard speak. He said, "You never actually finish a piece of work, you abandon it." And it's a little bit like that with this. As we thought about things as 20-year-olds, 30-year-olds, 40-year-olds in life, we were certain; as we got older, perhaps some of those certainties, some of those things, were challenged. I'm certainly in that position.
