You know what often doesn't get scheduled? Real work. Most of us use our calendars all wrong: we don't schedule work we schedule interruptions. One of the best explanations I've run across for why time blocking is important comes from Eric Barker, author of Barking Up the Wrong Tree, in an article for Observer: The value here is that it helps you build your day around your priorities-and by scheduling your time in advance, you're able to say no to non-priorities. Instead of completing your tasks whenever you find time, you schedule tasks on your calendar in advance. Time blocking is a simple productivity method that actually takes this into account.
