"What is the point in worrying oneself too much about what one could or could not have done to control the course one's life took? Surely it is enough that the likes of you and I at least try to make our small contribution count for something true and worthy. And if some of us are prepared to sacrifice much in life in order to pursue such aspirations, surely that is in itself, whatever the outcome, cause for pride and contentment."
