Failure is probably the most fatiguing (令人疲劳的)experience a person ever has. There is nothing more tiring than not succeeding, being blocked, not moving ahead. It is an evil circle. Failure causes fatigue, and fatigue makes it harder to get to work, which adds to the fatigue.

We experience this tiredness in two main ways: start-up fatigue and performance fatigue. In the former case, we keep putting off a task that we are forced to take up. Either because it is too boring or because it is too difficult, we avoid it. And the longer we put it off, the more tired we feel.

Such start-up fatigue is very real, even not actually physical, not something in our muscles and bones. The remedy (治疗法) is obvious, though perhaps not easy to apply: willpower exercise. The moment I find myself turning away from a job, or putting it under a pile of things I have to do, I clear my desk of everything else and attack the difficult item first. To prevent start-up fatigue, always treat the most difficult job first.

Performance fatigue is more difficult to handle. Here we are willing to get started, but we can't seem to do the job right. Its difficulties appear to be insurmountable and however hard we work, we fail again and again. The mounting experience of failure carries with it an ever-increasing burden of mental fatigue. In such a situation, I work as hard as I can, then let the unconsciousness take over.
