Ideally for whom? standards of beauty, as standards of everything, serves as aspirations, something to aim for, I see nothing wrong with that.
There is nothing wrong with it. I just think the standards of beauty in particular are rather limiting and pointless. Sure there's exercise, diet, and skincare, but most people will never reach the whatever standard there is. In terms of beauty, it just seems that it's really more based on luck of the draw than other types of aspirations. I guess you can go for plastic surgery
. Also, if you look across cultures, it's clear to me that a lot of what is considered beautiful is really cultural conditioning. Some cultures think painting your teeth black looks great. So there really is no objective standard of beauty and wouldn't the world be boring if everyone looked the same?
I think a lot of times people miss dating opportunities because what they consider beautiful is so limited. I use to only like the conventionally good looking people too, but after some self mental training, I am more able to appreciate all kinds of people. The types of looks that I like have been expanded several times. If you can get the conventionally good looking partner and have that partner be compatible with you in all other ways than sure, good for you. If you can't and still can't appreciate different types of looks, then well that sucks for you.
