Which is probably a good strategy. Not optimal, but better on average than blindly following the advice.
People are sometimes bad in predicting what will make them react which way. If you marry someone, at least you know your current set of trait made you attractive to them, and made them want to spend their time with you. There is no such guarantee for the proposed new set of traits.
Typical failure: In far mode it seems like a good idea that a man should have more ambition, and do what he can to progress on the carreer ladder. But that has some side effects, such as working longer hours, more stress, less attention to what happens at home; even some personality changes. And that is often resented in near mode, and sometimes leads to a divorce.
(I'm currently reading "Why Men Are the Way They Are" by Warren Farrell, and there one man describes his story of following all the advice people around him gave him... finishing with: I worked really hard to become a person whom everyone hates, including myself.)
I can't find an appropriate post at the moment, but I'm pretty sure Ferrett Steinmetz writes about him and his wife working to improve each other-- a difficult and contentious process, but useful.
Do you think there's no chance of partners having blind spots in different areas and using this so that eventually both can see more clearly?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
