“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.”

“When in doubt, check if your actions are aligned with your purpose.”

“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.”

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

“One way to stop worrying and get the courage to begin is to plan and prepare thoroughly in advance. Set clear goals and objectives, then gather information. Read and research books and blogs in your chosen field. Write out detailed plans of action, and then take the first step towards relieving stress.”

“An average person with average talent, ambition and education can outstrip the most brilliant genius in our society, if that person has clear, focused goals.”

“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.  ”

“Commit yourself to lifelong learning. The most valuable asset you'll ever have is your mind and what you put into it.”

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

“It is impossible to succeed without failing.” 

“The seventh key is that you must have a major definite purpose for your life. You must have one goal that, if you accomplish it, can do more to help you improve your life than any other single goal.”

“You become what you think about most of the time”

“Courage is not absence of fear; it is control of fear, mastery of fear.”

“You'll always get out of life what you put in-and you control what you put in.”

“if you expect to be successful, you will eventually be successful. If you expect to be happy and popular, you will be happy and popular. If you expect to be healthy and prosperous, that is what will happen... Always think and talk positively about the future. Start every morning by saying: 'I believe something wonderful is going to happen to me today.' Then, throughout the day, expect the best.”
