I do play football no-holds-barred. Any edge I can get, I'll take. I'd grab a face mask only in a fit of anger. Uncontrolled anger is damn near insane.

Winning the Super Bowl was obviously a great one, but the joy I felt of going to the Super Bowl, it was what I felt about the Pittsburgh Steelers and where we came from, the history of us to that point.

For a football coach, there's nothing that matches the pain of a team not playing up to its capabilities.

You can go to the bank and borrow money, but you can't go to the bank and borrow a Super Bowl ring. The ring is like a crown.

Grassroots organizing tends to be most available to big campaigns, but it's actually most useful to small ones. You can't win a presidential campaign without going on TV, but you can win a local election simply by organizing your community. NationBuilder levels the playing field.

Everyone knows the presidential candidates and has an opinion about them. But as you get to smaller races, that evaporates and you can win through sheer elbow grease.

If you had told me when I was at high school that one day I would be working for a for-profit company, let alone running one, I would have said you were crazy. But I am interested in how you can empower individuals to make change, and Causes is doing just that.
