“Ask yourself: Are you spending your time on the right things? You may have causes, goals, interests. Are they even worth pursuing? I've long held on to a clipping from a newspaper in Roanoke, Virginia. It featured a photo of a pregnant woman who had lodged a protest against a local construction site. She worried that the sound of jackhammers was injuring her unborn child. But get this: In the photo, the woman is holding a cigarette. If she cared about her unborn child, the time she spent railing against jackhammers would have been better spent putting out that cigarette.”
