“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.”

“The biggest enemies we have to overcome on the road to success are not lack of ability and lack of opportunity but fears of failure and rejection and the doubts that they trigger.”

“Imagine no limitations; decide what's right and desirable before you decide  what's possible.”

“There is one quality that one must possess to win, and that is definiteness of purpose, the knowledge of what one wants and a burning desire to achieve it.” 

“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.”

“Your life only gets better when you get better.” 

“When you allow yourself to begin to dream big dreams, creatively abandon the activities that are taking up too much of your time, and focus your inward energies on alleviating your main constraints, you start to feel an incredible sense of power and confidence.”

“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.”

“No one lives long enough to learn everything they need to learn starting from  scratch. To be successful, we absolutely, positively have to find people who  have already paid the price to learn the things that we need to learn to achieve  our goals.”

“Success is the ability to solve problems as well. A goal or an objective unachieved, in any area, is merely a problem unsolved. This is why a systematic approach to problem solving, one that works at a higher level and more consistently, is absolutely vital for you to achieve the maximum success that is possible for you. Think”

“Whatever you believe, with feeling, becomes your reality.”

“Help yourself warm up and prepare mentally by repeating, “I feel happy! I feel healthy! I feel terrific!” It is not possible for you to talk positively to yourself, using words like this, without immediately feeling happier and more confident.”

“It takes only about 10 to 12 minutes for you to plan out your day, but this small investment of time will save you up to two hours (100 to 120 minutes) in wasted time and diffused effort throughout the day.”

“Your most valuable asset can be your willingness to persist longer than anyone else.”

“In Re-framing, you interpret the event in a positive way. You change your language . Instead if defining it as a problem you re-frame it as a situation . A problem is something that is upsetting and stressful. A situation is something that you simply deal with .”
