"This would be a tricky operation, no doubt of that, and a mistake would probably be fatal. So many things he had done over the years would have been fatal, had his luck not been strongly good. He had cheated death dozens of times, but that did not mean he could take it as a given. A man needed only one fatal mistake to end the game."

How can a man be satisfied to entertain an opinion merely, and enjoy it? Is there any enjoyment in it, if his opinion is that he is aggrieved? If you are cheated out of a single dollar by your neighbor, you do not rest satisfied with knowing that you are cheated, or with saying that you are cheated, or even with petitioning him to pay you your due; but you take effectual steps at once to obtain the full amount, and see that you are never cheated again.

— Henry David Thoreau
