Turn It OffThe verdict is in. Technology is addictive, say the researchers, and answering and checking messages incessantly can drive impulsive behavior and stress. You need to control the devices, instead of the other way around, to be able to bring full attention to your work and decisions and clear space for your life. Turn off the BlackBerry and check it manually. Don't check e-mail at home. Make sure you have daily disconnect time to remove yourself from the fray. Send less mail. Ask before you click: Is this message critical? Does it rise to the importance of a phone call? Are you sending the message because you can? Congratulate yourself on how many messages you resist sending each day.
