Failure is probably the most exhausting experience a person ever has. There is nothing more tiring than not succeeding.
We experience this tiredness in two ways: as start-up fatigue(疲惫) and performance fatigue. In the former case, we keep putting off a task because it has either too boring or too difficult. And the longer we delay it, the more tired we feel.
Such start-up fatigue is very real, even if not actually physical, not something in our muscles and bones. The solution is obvious though perhaps not easy to apply: always handle the most difficult job first.
Years ago, I was asked to write 102 essays on the great ideas of some famous authors. Applying my own rule, I determined to write them in alphabetical(按字母顺序), never letting myself leave out a tough idea. And I always started the day’s work with the difficult task of essay-writing. Experience proved that the rule works.
Performance fatigue is more difficult to handle. Though willing to get started, we cannot seem to do the job right. Its difficulties appear so great that, however hard we work, we fail again and again. In such a situation, I work as hard as I can-then let the unconscious take over.
When planning Encyclopaedia Britannica (《大英百科全书》), I had to create a table of contents based on the topics of its articles. Nothing like this had ever been done before, and day after dat I kept coming up with solutions, but none of them worked. My fatigue became almost unbearable.
One day, mentally exhausted, I wrote down all the reasons why this problem could not be solved. I tried to convince myself that the trouble was with the problem itself, not with me. Relived, I sat back in an easy chair and fell asleep.
An hour later, I woke up suddenly with the solution clearly in mind. In the weeks that followed, the solution which had come up in my unconscious mind provided correct at every step. Though I worked as hard as before, I felt no fatigue. Success was now as exciting as failure had been depressing.
Human beings, I believe must try to succeed. Success, then, means never feeling tired.
People with start-up fatigue are most likely to（）.
A. delay tasks
B. work hard
C. seek help
D. accept failure

Several years ago, while attending a communication course, I experienced a most unusual process. The instructor asked us to list anything in our past that we felt 16 of, regretted, or incomplete about and read our lists aloud. This seemed like a very 17 process, but there's always some brave soul in the crowd who will volunteer. The instructor then 18 that we find ways to 19 people, or take some action to right any wrongdoings. I was seriously wondering how this could ever 20 my communication. Then the man next to me raised his hand and volunteered this story: “Making my 21 , I remembered an incident from high school. I grew up in a small town. There was a Sheriff none of us kids liked. One night, my two buddies(老兄) and I decided to play a 22 on him.” “After drinking a few beers, we climbed the tall water tank in the middle of the town, and wrote on the tank in bright red paint: Sheriff Brown is a FOX. The next day, almost the whole town saw our glorious 23 . Within two hours, Sheriff Brown had us in his office. My friends told the truth but I lied. No one 24 found out.” "Nearly 20 years later, Sheriff Brown’s name 25 on my list. I didn't even know if he was still 26 . Last weekend, I dialed the information in my hometown and found there was a Roger Brown still listed. I tried his number. After a few 27 , I heard, “Hello?” I said, “Sheriff Brown?” Paused “Yes”. “Well, this is Jimmy Calkins.” “And I want you to know that I did it.” Paused. “I knew it!” he yelled back. We had a good laugh and a 28 discussion. His closing words were: “Jimmy, I always felt bad for you because your buddies got it off their chest, but you were carrying it around all these years. I want to thank you for calling me … for your sake.” Jimmy inspired me to 29 all 101 items on my list within two years, and I always remember what I learned from the course: It's never too late to 30 the past wrongdoings.
