It is amazing to still see how many people have their email popping up, interrupting them from whatever they are doing.
By not turning off the notifications, you are basically telling yourself that whatever you have chosen to do proactively is not as important as anyone else’s request for your time. Either that, or the work you are doing is so boring that you welcome any respite in the form of a reactive interruption.
This is no way to work. Or live.
Kill the interruptions and do some great work.
