You don't know what it means to live the life that you could have lived, if an event over which you have no control, an unforeseeable circumstance, had not distracted and diverted you, and at times crushed you, as has happened to me. - Luigi Pirandello
Prepare for the unknown by studying how others in the past have coped with the unforeseeable and the unpredictable. - George S. Patton Jr.
