Some people say that promises are made to be broken. That certainly seems to be true in this cutthroat society that we live in. But if you break your promise, you will ruin your reputation and no one will trust you anymore. So whenever we say, "I give you my word," we should mean it. There is nothing worse than to be let 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 sure we can live up to. In short, therefore, to be trustworthy, we should always say what we mean and mean what we say.
