     If you do not use your arms or your legs for some time, they become weak; when you start using them

again, they slowly become strong again. Everybody 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 else says that his memory is poor, he really means

that 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 own fault (过错). But if he tells us that he has a poor memory, many of us think that his

parents are to blame (受责备), and few of us know that it is just his own fault. Have you ever found that some

people can't read or write but usually they have better memories? This is because they cannot read or write and

they have to remember things; they cannot write down in a little notebook. They have to remember days,

names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good

memory, learn from the people: Practice remembering.
