69. Mean What You Say p.476

（单词翻译）

　　Some people say that promises are made to be broken. That certainly seems to be true in this cutthroatsociety that we live in. But if you break your promise, you will ruin your reputation¹ and no one will trustyou anymore. So whenever we say, "I give you my word," we should mean it. There is nothing worse than to belet down by others because they have not kept their promises.
In fact, it isn't so difficult to keep promises. Just remember never to promise anything we are not surewe can live up to. In short, therefore, to be trustworthy, we should always say what we mean and mean whatwe say.
