What does willy's personal philosophy in life deal with?

Answer: Willy believes that, provided he works hard, he will be successful.

Explanation:

Death of a Salesman is a 1949 play written by Arthur Miller. The play tells the story of a man named Willy, and his attempt to provide for his family and leave a legacy after his death.

Willy's personal philosophy is that if he works hard and is persistent enough, his dreams will come true. He is convinced that if he believes in his dreams, he will be successful. Unfortunately, Willy learns that the reality is somewhat different, as there are obstacles to achieving our goals. There are inhibitions that prevent him from reaching financial security. As Willy lives in a world where success is embodied in the amount of money one has, his failure to conform to the society norms leads to his death. Willy's character, in this way, becomes a symbol for the failure of the American Dream during the post World War II era.
