I can't take the WSJ seriously anymore. They used to give my economics class in high school free copies every day (but then mysteriously stopped, hrmmm).
Also one of their bloggers swore he knew a billionaire who got 2-3 hours of sleep a night and worked hard every day, and had been doing it for ten years. Yeah, he'd be dead by then if that was true.
Granted, it was one of their bloggers, but the fact that they have a blogger who makes such ludicrous claims is ridiculous.
