That very concentration of vision and intensity of purpose which is the characteristic of the artistic temperament is in itself a mode of limitation. To those who are preoccupied with the beauty of form nothing else seems of much importance.
I’m struck again by the irony that spaceflight-conceived in the cauldron of nationalist rivalries and hatreds-brings with it a stunning transnational vision. You spend even a little time contemplating the Earth from orbit and the most deeply engrained nationalisms begin to erode. They seem the squabbles of mites on a plum.
Forget the career, do the work. If you feel what you are doing is on line and you're going someplace and you have a vision and you stay with it, eventually things will happen.
