I couldn’t agree more with Gabe’s last piece on notifications.
I also use the Do Not Disturb feature of iOS liberally. Whenever I walk into a meeting I toggle off the world. It’s a hugely underrated feature and easily accessed on iOS 8. Learn these settings. Browse the Notification settings in iOS too. Remove as many as you can get away with. It’s unlikely you need a notification at the exact time a package is delivered. It’s unlikely that your text editor has anything urgent you need to know. Avoid the constant and unnecessary pain created by too many green toggles.
