Living Within Your Means
「量力而为」

　　It is never a disgrace to say, 'I can not afford it.' It is shameful to commit yourself to expenditure you know you can not really afford and should not make – just because someone else urges you to go against your own better judgment. I have respect for the person for who can say without any self-consciousness at all, simply and cheerfully, 'I can not afford it.' But I hate to hear a long-drawn-out explanation of why . As a matter of fact, we should never demand to know why a person can not spend money on something he says he can not afford unless there is s sound reason for his finding some way to afford it. Then you may, if you feel you should, try to show him that way, quietly and without irritating him.
