I think that has to do with my awareness that in a sense we all have a certain measure of responsibility to those who have made it possible for us to take advantage of the opportunities. The door is opened only so far. If some of us can squeeze through the crack of that door, then we owe it to those who have made those demands that the door be opened to use the knowledge or the skills that we acquire not only for ourselves but in the service of the community as well. This is something that I guess I decided a long time ago.
