Answer:
Elie Wiesel repeats the words "you are too skinny, you are too weak" as a form of self encouragement and trying to motivate himself through the trials.
Step-by-step explanation:
Elie Wiesel was one of the survivors of the holocaust which led to the writing of his memoir "Night". In it, he details how they, as prisoners, were treated and had to suffer the worse of punishments at the hands of the brutal Nazis.
During one such experience at the concentration camps, he had to run before the SS doctors t show his qualification. He mentions that he kept repeating "you are too skinny, you are too weak" to encourage himself to push himself harder and to overcome the difficulties. By means of 'mental self torture', he is giving himself the much needed push and encouragement. Turning these negativity into something positive, he is making sure that he doesn't succumb to the pressures of his enemies. This repetition stands as a means of overcoming trials by oneself, no matter how harsh the condition may be, aiming at the long- term result.
