FDS encourages us not to lower our standards, but honestly, certain types of men are usually only open to dating certain types of women (e.g. very rich men only be willing to date other rich or very attractive women). While FDS tells us not to lower our standards, only being open to dating men seen as being at the top of the social hierarchy and "waiting" for such a man to ask you out may lead to being single forever despite how there are other HVM interested in you. It's sort of like only applying for a job at your favourite company instead of expanding your job search. How much do "leagues" matter in picking a partner and how can you know if your standards are too unrealistic?
