“Perhaps the most important insight of all with regard to success is that to achieve greatly, you must become a different person. It is not the material things you accomplish or acquire that matter so much as it is the quality of the person you must become to accomplish well above the average. The development of self-discipline is the high road that makes everything possible for you.”

“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 only real limitation on your abilities is the level of your desires. If you  want it badly enough, there are no limits on what you can achieve.  ”

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

“You can get your time and your life under control only to the degree to which you discontinue lower-value activities.”

“I found that every single successful person I’ve ever spoken to had a turning point and the turning point was where they made a clear, specific, unequivocal decision that they were not going to live like this anymore. Some people make that decision at 15 and some people make it at 50 and most never make it at all.”

“Leaders think and talk about the solutions. Followers think and talk about the problems.”

“feel their self-worth is pretty high, so that they can achieve; so that they can take on the world—so”

“Your mental picture of yourself has a powerful effect on your behavior. Visualize yourself as the person you intend to be in the future. Your self-image, the way you see yourself on the inside, largely determines your performance on the outside. All improvement in your outer life begins with improvements in your mental pictures, on the inside.”

“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.” 

“If it’s to be, it’s up to me!”

“The success you are enjoying today is the result of the price you have paid in the past.”

“Never say anything about yourself you do not want to come true.”

“Changing habits that are no longer consistent with your higher purposes is one of the hardest things you’ll ever do, and one of the most essential to the quality of your life.”

“Before you begin work, always ask yourself, "Is this task in the top 20 percent of my activities or in the bottom 80 percent?”
