“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.

“Know What You Believe What are your values today with regard to your work and your career? Do you believe in the values of integrity, hard work, dependability, creativity, cooperation, initiative, ambition, and getting along well with people? People who live these values in their work are vastly more successful and more highly esteemed than people who do not. What are your values with regard to your family? Do you believe in the importance of unconditional love, continuous encouragement and reinforcement, patience, forgiveness, generosity, warmth, and attentiveness? People who practice these values consistently with the important people in their lives are much happier than people who do not. What are your values with regard to money and financial success? Do you believe in the importance of honesty, industry, thrift, frugality, education, excellent performance, quality, and persistence? People who practice these values are far more successful in their financial lives than those who do not, and they achieve their financial goals far faster as well. What about your health? Do you believe in the importance of self-discipline, self-mastery, and self-control with regard to diet, exercise, and rest? Do you set high standards for health and fitness and then work every day to live up to those standards? People who practice these values live longer, healthier lives than people who do not.”

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

“Refuse to complain about your problems. Keep them to yourself. As speaker-humorist Ed Foreman says, "You should never share your problems with others because 80 percent of people don't care about them anyway, and the other 20 percent are kind of glad that you've got them in the first place.”

“...you cannot eat every tadpole and frog in the pond, but you can eat the biggest and ugliest one, and that will be enough, at least for the time being. ”

“If you envy successful people, you create a negative force field of attraction  that repels you from ever doing the things that you need to do to be successful.  If you admire successful people, you create a positive force field of attraction  that draws you toward becoming more and more like the kinds of people that  you want to be like.”

“How shall we live in order to be happy?” Your ability to ask and answer that question correctly for yourself—and then to follow where your answer leads you—will largely determine whether you achieve your own happiness, and how soon.”

“It is rather pointless to go head to head with strong and entrenched competition. But numerous opportunities can be found in the marketplace for a company to maximize its unique qualities, differentiate its products and services, and go after a specific market segment where its competitors are weak and where you can develop superiority, where you can win battles.”

“human resources are the most valuable assets that the company has.”

“Committing your goals to paper increases the likelihood of your achieving them by one thousand percent.”

“There is an old saying that "by the yard it's hard; but inch by inch, anything's a cinch!”

“Fortunately, courage can be developed by acting courageously. When you do something that you fear, you feel more courageous. In life, the courage follows the courageous behavior. You become courageous by acting courageously, even when you do not feel like it. Emerson also wrote, “Do the thing and you will have the power.” Don’t be afraid to make hard decisions, especially with regard to people and expenses.”

“By concentrating single-mindedly on your most important task, you can reduce the time required to complete it by 50 percent or more. It has been estimated that the tendency to start and stop a task—to pick it up, put it down, and come back to it—can increase the time necessary to complete the task by as much as 500 percent. Each time you return to the task, you have to familiarize yourself with where you were when you stopped and what you still have to do. You have to overcome inertia and get yourself going again. You have to develop momentum and get into a productive work rhythm. But when you prepare thoroughly and then begin, refusing to stop or turn aside until the job is done, you develop energy, enthusiasm, and motivation. You get better and better and more productive. You work faster and more effectively.”

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

“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.”
