We need something to believe in. Doesn't matter what. God, Buddha, Elvis. We all need faith. That's what gives us hope, hope there's something better out there, something to strive for. Hope is what drives you. Hope gets you out of bed, hoping you're going to make that big sale at work, hoping you get to make love to your wife at night. - Paul Busch
