We believe in the art of war. We are trying to get our competition to attack us with angry, virulent energy, so we can transform that into larger market share.

I also think that employees these days expect less of a separation of work and personal life. That doesn't mean that work tasks should encroach upon our personal time, but it does mean that employees today expect more from the companies for whom they work.
