Beauty
How important is your appearance? Although everyone wants to be good-looking, are beautiful people always happier people? For example, it must be a problem to be a really beautiful woman, because some men may be more interested in looking at you than talking to you. They think of you as a picture rather than a person. There are also some people who think that women who are exceptionally pretty and men who are particularly handsome must be stupid. They believe that only unattractive people can be intelligent.
On the other hand, no one wants to be really ugly, and have a face that nobody wants to look at; and no one wants to be plain either — that is to be neither attractive nor unattractive, and have a face that is easily forgotten.
Being attractive is like being rich — it can help you find happiness, but it doesn't always make you happy. So maybe the best thing is not to worry about how you look, but simply try to be an interesting person. For interesting people have interesting faces, and interesting faces are almost always attractive.
