" Africa was full of people in need of help and there had to be a limit. You simply could not help everybody; but you could at least help those who came into your life. That principle allowed you to deal with the suffering you saw. That was your suffering. Other people would have to deal with the suffering that they, in their turn, came across. "

― Alexander McCall Smith , Morality for Beautiful Girls (No. 1 Ladies' Detective Agency #3)
