Let's see in short category form:
I'm not having surgery to make myself acceptable to someone
I'm not going to change my values to make myself acceptable to someone
I'm not going to invest in a relationship based on my ability to change in order to progress the relationship
I'm not going to change habits that I know are good and necessary for me (going to church, brushing teeth, etc)
Basically this. For the most part, take it or leave it. If they are very invested in a particular hobby, I might try that out.
