When to Quit
To know when to quit. Whether to give up - this is often the question facing the gambler. No one is taught the art of walking away. And the anguish of deciding if I should keep playing is hardly unusual. Will I be able to quit honorably? Or am I the type who waits stubbornly for something to happen? something like, for instance, the end of the world? Or whatever it might be, maybe my own sudden death, in which case my decision to give up would be beside the point.
