晶闸管工作在大功率状态下，其损坏因素很多，为保证可靠实用经常采用的过压保护是（）。A

When something goes wrong, it can be very satisfying to say, “Well, it’s so-and-so’s mistake.” or “I know I’m late, but it’s not my fault; the car broke down.” It is probably not your mistake, but once you form the habit of blaming (指责) somebody or something else for a bad situation, you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.

Winners are great at solving problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague (同事) causes you problems on the job for being short of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don’t depend on the person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.

This is what being a winner is all about – creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and chances to develop their own talents. So, stop focusing on “whose mistake it is.” Once you are confident about your power over bad situations, problems are just stepping stones for success.
