1. Dr. William James, Father of American psychology: Everything in our lives is controlled by our attitudes. Life is not so much a matter of position as a matter of disposition. 2. Proverbs, a writer of the Bible book,: We should all realize that potential remains potential until it expresses itself through action. The attitude we put out is what we get back.. 3. Robert Matchup, the famous movie star,: No matter what you do, do your best at it. If you are going to be a bum, be the best bum there is. 4. Samuel Jackson,: He who seeks happiness by changing anything but his own disposition will waste his life in fruitless efforts. 5. Steven Hawking: Circumstances may seem beyond your control however you do have full control over your responses to circumstances. It’s your attitude not your aptitude( 能力)that will determine your final altitude. 6. Victor Frankel ,the distinguished Jewish psychologist,: Whenever something happens which makes you angry ,neutralize the negative thoughts by focusing your thoughts on your goals. It’s a good idea, when this happens, to take your goals list out that carry with you ,and read it. Also repeat to yourself,” I am responsible, I am responsible” 7. Charles Swindle: The longer I live ,the more I realize the impact of attitude on life. Attitude to me, is more important than the past, than education, than money, than circumstances, than failures, than successes, than what other people think or say or do. It’s more important than appearance, giftedness or skill. It will make or break a company···a church···a home .The remarkable thing is we have a choice every day regarding the attitude we will embrace for that day. We cannot change our past···We cannot change the fact that people will act in a certain way. We cannot change the inevitable···I am convinced that life is 10% that happens to me and 90% how I react to it. And so it is with you···We are in charge of our attitudes. 8. Those who know don’t speak, whose who speak don’t know. 9. The whole of science is nothing more than the refinement of everyday thinking. 10. It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to fit facts. 本文来源：https://www.wddqw.com/doc/a40f301931126edb6f1a1037.html
