“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.”

“Our greatest enemies are always our own doubts and fears. But there are no limits to what you can do, be, or have except for the limits you place on yourself.”

“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.”

“Love only grows by sharing. You can only have more for yourself by giving it away to others.”

“Your future largely depends on what you learn and practice from this moment onward.”

“Life is like a combination lock; your job is to find the numbers, in the right orders, so you can have anything you want.”

“If you can get yourself to read 30 minutes a day, you're going to double your income every year.”

“Between you and every goal that you wish to achieve, there is a series of obstacles, and the bigger the goal, the bigger the obstacles. Your decision to be, have and do something out of the ordinary entails facing difficulties and challenges that are out of the ordinary as well. Sometimes your greatest asset is simply your ability to stay with it longer than anyone else.”

“It is impossible to succeed without failing.” 

“Josh Billings once wrote, “It ain’t what a man knows what hurts him. It’s what he knows what ain’t true.”

“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.”

“If you don't set goals for yourself, you are doomed to achieve the goals of someone else.”

“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.”

“Get it 80 percent right and then correct it later." Run it up the flagpole and see if anyone salutes. Don't expect perfection the first time or even the first few times. Be prepared to fail over and over before you get it right. The biggest enemies we have to overcome on the road to success are not a lack of ability and a lack of opportunity but fears of failure and rejection and the doubts that they trigger. The only way to overcome your fears is to "do the thing you fear,”

“The more you discipline yourself to use your time well, the happier you will feel and the better will be the quality of your life in every area.”
