I guess the way I look at it, is that I don't know if my consciousness can be extinguished or harmed or not.
But I know that I can waste my life by not pursuing my dreams. So as long as I am aware and have a physical body and the ability to exercise my will, I will do so in pursuing my dreams. Helping other people along the way, is an important part of it, making a positive impact on the world is an important part of it.
But in the end its my dream, and the pursuit of it is being directed by me, so is it self centered?
I mean I could say, that I want to be above all "others centered" and be indifferent as to what I do as long as it helps others. Wherever the greatest need in the world is I will be thee seeking to fill it.
I feel I used to be on a path like that at one time and found it unsatisfying.
