You can not really get someone to be less selfish, whether she is your best friend, enemy, classmate, etc. If they are selfish, then their selfishness is already in their personality, and you can't really do anything about it.

Self-obsessed is when somebody cares more about themself than other people. Selfish is being greedy, or hording something, money for instance. These two are very different. Actually, I would think they are generally the same. To me when a person is selfish they are also self obsessed and vice verse. There is such a wide range of things that one can be selfish or obsessed about and the question was the difference between self-obsessed so the answer is nothing. A selfish person is "selfish" and a "self" obsessed person is "selfish". To me they are the same thing. Its anything that has to do with that person that's usually what rules their world. These type people are also greedy, very needy, attention seekers and usually extremely narcissistic.
