As we all know, if you don’t use your arms or your legs for some time, they will become weak; when you start using them again, they slowly become strong again. Everyone knows that. Yet many people do not seem to know that memory works in the same way.
When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone says that his memory is poor, he really means he does not give it enough chance to become strong.
If a friend says that his arms and legs are weak, we know that it is his fault(过错). But if he tells us that he has a poor memory, many of us think that their parents are to blame(怪责), and few of us know that it is just his own fault.
Have you ever found that some people can’t write or read (blind people) but they have better memories? This is because that they can’t read or write and they have to remember things. They cannot write them down in a small notebook. They have to remember days, names, songs or stories, so their memories are being exercised the whole time. If we want to have a good memory, we should practise remembering things.
