Does it really work for women to "change" their men?

How to groom, what to say, what to like/dislike…..Are there any success-stories of women changing or moulding their boyfriends/husbands where both are happy with the result (not just content or satisfied with the compromise)?
And if a person changes drastically…..are you still attracted to them or were you not attracted to the ‘raw material’ but rather the potential?
