Willy and joy

Like Willy, my father is a salesman. He is a good salesman but if asked will admit to not enjoying his work. Thinking on this, I began to wonder if Willy really enjoyed his job. I believe that Willy took pleasure in completing a sale and climbing up the “corporate ladder” but I am not sure he liked the actual sales routine. Willy is clearly a man who is missing a piece of something in his life. I am not sure yet what he is missing. Does Willy miss his youth or possibly crave guidance he never received from his older brother and absent father?
