"The time to worry is three months before a flight. Decide then whether or not the goal is worth the risks involved. If it is, stop worrying. To worry is to add another hazard. It retards reactions, makes one unfit. . . . Hamlet would have been a bad aviator. He worried too much."

 (Amelia Mary Earhart, aviatrice; Atchison, 24 luglio 1897 – Oceano Pacifico, 2 luglio 1937)
