Suppose you came upon someone in the woods working to saw down a tree. They are exhausted from working for hours. You suggest they take a break to sharpen the saw. They might reply, " I didn't have time to sharpen the saw, I'm busy sawing!"
Habit 7 is taking the time to sharpen the saw. By renewing the four dimensions of your nature - physical, spiritual, mental and social/emotional, you can work more quickly and effortlessly. To do this, we must be proactive. This is a Quadrant II (important, not urgent) activity that must be acted on. It's at the center of our Circle of Influence, so we must do it for ourselves.
