Legendary,

That is one of the best questions I've ever seen on GLP.

The opposite of Self centeredness is Truth centered-ness. You should seek to know the truth and begin to love the truth more than your opinions. When I say truth, I'm talking about what is in accordance with reality. For example, you should know that any given person's opinion about brain surgery doesn't mean a whole lot unless it aligns to what is actually true about brains. If a person doesn't care about what is true and goes to operate on a brain, the patient dies.
The same is true in your relationships with other people. There is a correct way to interact with a person in order to have a healthy relationship. If a person violates that the relationship begins to suffer and eventually dies.

If you understand what love really is (to want what is right more than anything else), then you can begin to judge your actions against that standard. If you do this, you will quickly find two things that hamper that correct motive - the need for significance and the need for love and acceptance. These emotional needs, when not properly met and managed, are the source of self centeredness. Men typically want so badly to be significant that they do things they shouldnt or that are harmful. Women want to be loved and accepted so bad that they do the same. These needs begin to drive people and most people don't even know why they're doing what they're doing. If you recognize these fundamental needs within yourself and seek to become do what is right and best instead of constantly feeding these needs - you will become purpose centered instead of self centered.
