A central dogma of many time management and personal productivity systems is that you need to expend more of your time doing those activities that are more crucial for reaching your goals, and less time doing those matters that are more insignificant. You must invest most of your time each week doing what you do best, and let other people do what they do best. Assigning some of your tasks to other people (maybe more qualified) individuals can free up your time and energy to follow up on your highest priority goals. For example, you may choose to hire an accountant instead of preparing your taxes yourself, thereby freeing up a couple of hours of your time and perhaps reducing stress. Naturally, each of us has to work out the value of one’s time versus the economic cost of hiring somebody to do yard work, home repairs, and so on.
