Attitude, to me, is  16   important than facts. It is more important than the past, than education, than money, than circumstances, than failures, than successes, than 17    other people think, say, or do. It is more important than appearance, giftedness, or skill. It will make or break a company, a church, a home. The 18    (remark) thing is we have a choice every day regarding the   attitude we will embrace(接受) for that day. We cannot change 19  past. We cannot change the 20   that people will act in a certain way. We cannot change 21   inevitable(不可避免的). The only thing we can do is 22   (play) on the one string we have, and that is our attitude. I am convinced 23    life is 10% what happens to me and 90% how I react to it. 24   so it is with you. We are  25    charge of our attitudes.
