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.
