“The first requisite for success is the ability to apply your physical and mental energies to one problem incessantly without growing weary.”

“Never talk about the content. Talk about the outcome.”

“To be truly happy and fulfilled, you must be working toward accomplishing something that is bigger than yourself, and that makes a difference in the life or work of others.”

“It is not failure itself that holds people back; it is the fear of failure that paralyzes you.”

“Practice "zero-based thinking" in every part of your life. Ask yourself continually, "If I were not doing this already, knowing what I now know, would I start doing it again today?" If it is something you would not start again today, knowing what you now know, it is a prime candidate for abandonment or creative procrastination.”

“Become the kind of leader that people would follow voluntarily; even if you had no title or position.”

“Move out of your comfort zone. You can only grow if you are willing to feel awkward and uncomfortable when you try something new.”

“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.”

“The more credit you give away, the more will come back to you. The more you  help others, the more they will want to help you.”

“The fact is that your productivity begins to decline after eight or nine hours of work. For this reason, working long hours into the night, although it is sometimes necessary, means that you are usually producing less and less in more and more time. The more tired you become, the worse the quality of your work will be and the more mistakes you will make. At a certain point, you can reach “the wall” and simply be unable to continue, like a battery that is run down.”

“Almost all stress, tension, anxiety, and frustration, both in life and in work, comes from doing one thing while you believe and value something completely different.”

“Your decision to be, have and do something out of ordinary entails facing  difficulties that are out of the ordinary as well. Sometimes your greatest asset is  simply your ability to stay with it longer than anyone else.”

“The happiest people in the world are those who feel absolutely terrific about themselves, and this is the natural outgrowth of accepting total responsibility for every part of their life.”

“If there is no solution, there is no problem.”

“You can make excuses or you can make progress. You choose.”
