    "When one of the doctors criticizes (批评) me, I get defensive.I feel like a child again, being scolded,

and I want to explain that I'm not wrong, " says Viola, a nurse.This is a common reaction to criticism, but

not a good one.There are better ways of dealing with criticism.

     Try to be objective (客观的). When Sol was criticized by his new employer for not having made a

sale, Sol's reaction was to feel sorry for himself."I had put everything I had into making that sale, " Sol

says."And I felt that I had failed as a person.I had to learn through experience not to react like that to

each fail ure."

     Take time to cool down.Rather than react at once to criticism, take some time to think over what was

said.Your first question should be whether the criticism is fair from the other person's position.The

problem may be a simple misunderstanding of what you did or your reasons for doing it.

     Take positive action.After you cool down, consider what you can do about the situation.The best

answer may be "nothing". "I finally realized that my boss was having personal problems and taking them

out on me because I was there, " says Sheila."His criticisms didn't really have anything to do with my

work, so nothing I said or did was going to change them." In Sheila's case, the best way to deal with it

was to leave her job.However, that's an extreme reaction.

     You may simply explain your opinion without expecting an indepth discussion.You may even decide

that the battle isn't worth fighting this time.The key, in any case, is to have a reasonable plan.
