I think it is someone who is centered on something besides themselves. You can feel it when you first meet them. It is like a magnet. We have a nurse at the hospital like that. When she walks in the room, you immediately feel better because you know she really cares about you. I called her "my caring angel". When you are selfish, your enjoyment is very short-lived. When you give of yourself to others, you can always look back and get enjoyment and fond memories of it.
