想让人愉快？很简单。

要传播喜悦，你必须拥有它。 要给予快乐，你自己或多或少必须是愉快的人。 令人愉快不是尝试让自己看起来愉快，而是做令你愉快的事情。 于是你令他人愉快。--艾伦沃茨

To spread joy, you have to have it. To impart delight, you have to be more or less delightful. And to be delightful is not some factor of trying to make yourself look delightful, it is to do things that are delightful to you. You thereby become delightful to others.
