“When a girl becomes what boys consider a good shiduch she will have an easier time ”
I disagree- sometimes it is the girl or boy who is a bit different who is looking for someone a bit different who will be easier to set up since their needs are better defined. It is those who are very typical, who are not any different than hundreds of other girls like them, who do not stand out on a list of other girls like them, and have to compete with hundreds of others for the same shidduchim that have it hard.
Also, it is never a good idea to “become” something that you are not just to get a shidduch.
