"Do everything right all the time and the child will prosper. It is as simple as that, except for: fate, luck, heredity, chance, the astrological sign he was born under, his order of birth, his first encounter with evil, the girl who jilts him in spite of his excellent qualities, the war being fought when he is a young man, the drugs he may try too many times, the friends he makes, how he scores on tests, how well he endures kidding about his shortcomings, how ambitious he becomes, how far he falls behind, circumstantial evidence, danger when it is least expected, difficulty in triumphing over circumstances, people with hidden agendas, and animals with rabies."
