Turning off all distractions for a half hour or hour of uninterrupted work does not have to only happen at your work. This can be a powerful tool for home too.
At a scheduled time on your calendar turn off the phone, TV, and email; then spend a half hour tidying the bedroom. Or schedule an hour to give your undivided attention to a loved one.
I know of people who make a calendar appointment to play with their kids. This seems very cold and mechanical. But is it cold to make a conscious effort to focus all your attention to your child, or is it cold to pay half attention to your child and half to responding to a text message from your boss?
