And what about smiles that are faked to the extend of feeling genuine just to hide true sadness because most wouldn't understand ones despair or care to ? Again, do not judge a book by its cover. Smiles can be polite, faked to obtain something (sales), pure happiness, a facade ....
About things that are considered nice, most are only designs following fashion. I never followed fashion, I wear a pocket watch and use 30yo keyboard and trackball. Stuff I like and find nice are considered old-fashioned and outdated. Should I not find them nice then because they are commonly considered as such ?
When I drive a car I care about how it behaves on the road not how it looks, when I listen to speakers or amp I care about how they sounds not how they look, I do not care if people like my clothes I want them to be comfy and to my taste. I like to eat my cheese with mustard on it and almost every one think it is non-sense.
If you want most people to find your design appealing, then you have to follow trends and forget about what you deeply feel. But then can it still be considered your design since it is only based on trends with a small fraction of your being in it ?
If someone is to design something that deeply express him(her)self, then chances are high it won't touch many souls. And people who will trully react to it the way, the designer wanted, will have a personnality built from experiences close to the designer's life.
