Listen. What's that sound? It's your heartbeat. Or a bird chirping. Or the crunching of fallen leaves under your feet. It's amazing what you can hear when you're not drowning your days with an iPod or the radio. The benefits are clear in terms of what happens economically and environmentally when you stop using your TV as background noise. But, you might also gain personally. Spend time with your thoughts. Come up with the next big thing. Take time to say 'Thank you.' By flipping the switch to 'off,' you'll be more aware of what's going on around you.
