“How shall we live in order to be happy?” Your ability to ask and answer that question correctly for yourself—and then to follow where your answer leads you—will largely determine whether you achieve your own happiness, and how soon.”

“The biggest mistake we could ever make in our lives is to think we work for anybody but ourselves.”

“The greatest problem of human life is fear. It is fear that robs us of happiness. It is fear that causes us to settle for far less than we are capable of. It is fear that is the root cause of negative emotions, unhappiness and problems in human relationships.”

“Anytime you stop striving to get better, you're bound to get worse.

“Discipline is what you must have to resist the lure of excuses”

“Concentrate all your thoughts on the task at hand. The sun’s rays do not burn until brought to a focus.” 

“Your thoughts, vividly imagined and repeated, charged with emotion, become your reality.”

“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.”

“It is rather pointless to go head to head with strong and entrenched competition. But numerous opportunities can be found in the marketplace for a company to maximize its unique qualities, differentiate its products and services, and go after a specific market segment where its competitors are weak and where you can develop superiority, where you can win battles.”

“Your subject should always answer the question “What is the problem to be solved?” or “What is the job to be done?” A”

“The starting point of great success in your life begins, in the simplest terms, when you discipline yourself to think and talk about only the things you want and refuse to think and talk about anything you don't want.”

“Discipline is what you must have to resist the lure of excuses. It is self-discipline that enables you to “vote yourself off the island.” It is the key to a great life and, without it, no lasting success is possible.”
