There Are Always a Million Distractions. Here's How to Silence the Noise and Pay Attention. Interruptions are the enemy of productivity.

It just may be the crime of the century. Our minds, thoughts and chief productivity tool--attention--are being stolen by a thief operating with absolute impunity: incessant, unbounded interruptions. An ever-growing volume of intruders--e-mail, texts, apps, phone calls, social media alerts--combined with assaults from increasingly time-panicked humans, are leaving few places safe for chirp-, chime- or ding-free concentration.

Information overload, which includes the recovery time from unnecessary interruptions, cost the U.S. economy $997 billion in 2010, according to Overload!: How Too Much Information is Hazardous to your Organization by Jonathan B. Spira. An Intel study found that lost productivity from information overload alone would cost $1 billion per year for a company its size.

Chronic intrusions shrink attention spans, drive stress by burning up mental and emotional resources and trigger mistakes. An interruption averaging 2.8 seconds--say, one of those blinking notifications in the corner of your computer screen--can double the risk of error, a study by researchers at Michigan State University and the U.S. Naval Research Laboratory found. Increase the duration of the interruption to 4.4 seconds, and you triple the chance of a mistake.
