By now, plenty of productivity experts have suggested a relatively simple solution for battling the distractions of the modern workday: resist the urge to constantly check your email or surf the Internet, and don’t answer the phone unless you have to.
Not so easy, is it? If you can’t resist the temptation and you work on a Mac you might want to check out a new application called Freedom. Freedom disables all wireless and Ethernet networking on your computer for a period of your choosing, up to three hours at a time. After that, it re-enables your network and restores things back to normal. And don’t think you can just up and cheat whenever you want to; according to the Freedom ReadMe:
Stopping or quitting Freedom will not re-enable your network adapters. This is purposeful. To re-enable your network before the time period elapses, you must restart your computer.
You’re on your own, however, when it comes to not answering the phone.
