" Dustin Wax says it well: No matter how organized you are, how together your system is, how careful you are about processing your inbox, making a task list, and working your calendar, if you don’t stop every now and again to look at the “big picture,” you’re going to get overwhelmed. You end up simply responding to what’s thrown at you, instead of proactively creating the conditions of your life.16 Find a time for your weekly review, add it to your calendar, and commit to doing it every week. I really can’t over-emphasize the importance of this discipline. "
