The 7th habit from the book The 7 Habits of Highly Effective People is all about preserving and enhancing the greatest asset we have-- ourselves. Sharpening the saw means regularly renewing the four dimensions of our nature: body, mind, heart, and spirit.
There's no other way you could spend an hour that would begin to compare with the Daily Private Victory of sharpening the saw in terms of value and results. It will affect every decision and every relationship. It will greatly improve the quality and the effectiveness of every other hour of the day, including the depth and restfulness of your sleep.
When learning to Sharpen the Saw, observe what other people do to renew themselves on a daily basis to see what you might learn and apply. Develop your own routine, pattern, or regimen for renewing yourself daily. Block out time to sharpen the saw when you do your weekly planning, and identify which dimension you may be falling short on-- body, mind, heart, or spirit-- and make it a focus this week.
As you renew yourself in each of the four areas, you create growth and change in your life. Sharpen the Saw keeps you fresh so you can continue to practice the other six habits and to thrive at work. You increase your capacity to produce and handle the challenges around you. Without this renewal, the body becomes weak, the mind mechanical, the emotions raw, and the person selfish. Not exactly thriving, is it?
