They seem to seek failure by not trying to win or   48  success.  By not trying, they always have a(n)   49 ：“I may have lost, but it doesn’t matter   50   I really didn’t try.”   51    , this belief is the same as    52  of the true competitors trying to prove themselves. Both are based on the   53   belief that one’s self-respect relies on how well one performs in    54   with others.  Both are afraid of not being valued. Only as this basic and often troublesome fear begins to dissolve（缓解）  55   a new meaning in competition.
