A wise counselor once said to a young man who was experiencing frustration and disappointment with his own professional success, “You do not have to set your goal to reach the moon in order to have success in traveling. Sometimes one can be very successful merely by taking a walk in the park, or riding the subway downtown,” the counselor added, “You have not really failed and spoilt your chances for success until you have been unsuccessful at something you really like, and to which you have given your best effort.” 本段中 “You have not really failed and spoilt your chances for success until you have been unsuccessful at something you really like, and to which you have given your best effort.”这句怎么翻译？
