Research Is a State of Mind① For many years,there has been much misunderstanding as to just what research is. The popular belief seems to be that there is something mysterious （神秘的） about it and every research requires expensive scientific equipment. Actually, this is not so. Research isn't a physical thing at all; it's a state of mind. It is a simple,organized way of trying to accomplish something you wish to do.② You start by selecting the problem. you would like to solve, and then you list at least ten reasons why it has not been solved. But in selecting the problem, you need to be sure that it is worth the effort. Remember, it takes just as much effort to solve a useless problem as a useful one.③After carefully selecting the problem and the ten things between you and the solution, you then use the same procedure as in solving a crossword puzzle （填字游戏）. You start with the less serious difficulties, and eventually you arrive at the one or two major ones. In the solution of the remaining difficulties, you may need some simple equipment,but what you need most is patience. Few people realize how hard it is to do anything new.④ Maybe one of the reasons people are so easily discouraged is because of their Education. During all our years at school, we were examined two or three times a year. If we failed once, we were out. However, all research work is 99.9% failure and, if we succeed once, we are in. If we are going to make progress, we must learn to fail intelligently so that we won't become discouraged at the 99.9% failure. One should make sure the research is_____.
