Earl Nightingale explains that you are the president of your own personal corporation. He says that even though the chemicals in your body are only worth a small amount of money, your true value comes from how you manage your life. You need to view yourself as a business owner who is fully responsible for your own success or failure. Your family members are like the stockholders in your company, and it is your job to make sure the value of their stock goes up as the years go by.
