All of us ought to be able to prepare for the predictable challenges and setbacks that crop up every day.If we expect that life won't be perfect, we'll be able to avoid an impelling force to quit.But even if you are strong enough to persist through the obstacle course of life and work, sometimes you will encounter an harmful event that will completely knock you on your back.

　　我们每个人都应做好准备迎接每天的挫折和挑战。如果我们相信生活并非十全十美，我们就能避免一时冲动放弃追求。但即使你意志坚强，能够挺过生活、工作中的困难，有时你也会遇到逆境，它会让你大吃一惊。
