完形补文（请将正确答案的完整形式拼写在空格处，注意大小写）Building success from the ashes of failureThere are several key abilities (able)that allow successful people to fail forward instead of __1__ (take) each setback personally. First, successful people don't blame __2__ (they) when they fail. They take __3__ (responsible) for each setback, but they don't take the failure personally. Second, successful people don't define themselves by individual __4__ (fail). They recognize that each setback is a small part of the whole. Third, achievers are willing to vary their __5__ (approach) to problems. That's important in every walk of life. If one approach doesn't work for you, if it brings __6__ (repeat) failure, then try something else. To fail forward, you must do what __7__ (work) for you, not __8__ (necessary) what works for other people. Finally, successful people are resilient. They don't let one error keep them down. They learn from their mistakes and move on.These points form a firm foundation for dealing with failure in all parts of life, __9__ (include) personal finance. As you pay off your debt, as you learn to invest, as you cut your spending, accept that some failure is inevitable. But you are not your mistakes. Own them, learn from them, and move on. And remember: Good habits keep small mistakes __10__ (manage).
