“You perform at your highest potential only when you are focusing on the most valuable use of your time. This is the key to personal and business success. It is the central issue in personal efficiency and time management. You must always be asking yourself, What is the most valuable use of my time right now? Discipline yourself to work exclusively on the one task that, at any given time, is the answer to this question. Keep yourself on track and focused on your most important responsibilities by asking yourself, over and over, What is the most valuable use of my time right now? How you can apply this law immediately: 1. Remember that you can do only one thing at a time. Stop and think before you begin. Be sure that the task you do is the highest-value use of your time. Remind yourself that anything else you do while your most important task remains undone is a relative waste of time. 2. Be clear about the most valuable work that you do for your organization. Whatever it is, resolve to concentrate on doing that specific task before anything else. Why are you on the payroll? What specific, tangible, measurable results are expected of you? And of all the different results you are capable of achieving, which are the most important to your career at this moment? Whatever the answer, this is where you must focus your energies, and nowhere else.”
