     One of my favorite posters says, "Life is a test. It is only a test. Had this been a real life, you would have

been instructed where to go and what to do." Whenever I think of this humorous bit of wisdom, it reminds

me not to take my life so seriously.

     When you look on life and its many challenges as a test, or series of tests, you begin to see each issue you

face as an opportunity to grow, a chance to discover more about life. Whether you're being bombarded with

problems, responsibilities, or even insurmountable (不能超越的) difficulties, when looked on as a test, you

always have a chance to succeed, in the sense of overcoming what is challenging you. If, on the other hand,

you see each new issue you face as a serious battle that must be won in order to survive, you're probably

meeting with a very rocky journey. The only time you're likely to be happy is when everything is working out

just right. And we all know how often that happens.

     As an experiment, see if you can apply this idea to something you are forced to deal with. Perhaps you

have much pressure from your parents or you have a demanding boss. See if you can redefine the issue you

face from being a "problem" to being a test. Rather than struggling with your issue, see if there is something

you can learn from it. Ask yourself, "Why is this an issue in my life? What would it mean and what would be

involved to overcome it? Could I possibly look at this issue any differently? Can I see it as a test of some kind?" 

     If you give this strategy (策略) a try, you may be surprised at your changed responses. It has become far

more acceptable to me to accept things as they are.
