“The ability to concentrate singlemindedly on your most important task, to do it well and to finish it completely, is the key to great success, achievement, respect, status, and happiness in life. This key insight is the heart and soul of this book.

“Nobody works better under pressure. They just work faster.”

“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.”

“Ideas are a mode of transportation, a vehicle that you can use to take yourself from wherever you are to wherever you want to go.”

“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.”

“Teamwork is so important that it is virtually impossible for you to reach the heights of your capabilities or make the money that you want without becoming very good at it.”

“The first rule of frog eating is this: If you have to eat two frogs, eat the ugliest one first.”

“Goals are the fuel in the furnace of achievement.”

“The Law of Forced Efficiency says, “There is never enough time to do everything, but there is always enough time to do the most important things.”

“The second rule of frog eating is this: If you have to eat a live frog at all, it doesn't pay to sit and look at it for very long.”

“If you have to eat two frogs, eat the ugliest one first." This is another way of saying that if you have two important tasks before you, start with the biggest, hardest, and most important task first.”

“Regla: el pensamiento a largo plazo mejora las decisiones de corto plazo.”

“Goals are the fuel in the furnace of achievement”

“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.”

“Epictetus, a Greek philosopher, once wrote, “Circumstances do not make the man. They merely reveal him to himself.”
