We have discussed how different characters in Death of a Salesman relate differently to each person who reads the play. Some connect to Willy, some to Charley, maybe some to Linda, but it all depends on what you personally bring to the story. I bring my experiences to connect with Biff the most.
Biff is the son who the most is expected out of. He is going to be the star child of the family. He will be the successful salesman or the greatest football player his father never was but always wanted. Biff, when he was a child, did everything that his dad told him would make him "well liked" in the world. Only after he discovers Willy's affair does Biff begin diverging from his father. Once this initiation has occurred, Biff realizes what he really wants out of life. The ambition to work with his hands and move out West takes the complete opposite direction of Willy.
My relation comes from the same view Biff has. I have always wanted to do things that my dad has said will make me successful. But now, as college approaches, I am unsure if that is really what I want. The career I desire could be more along the lines of computers and video games rather than engineering. I don't know how I will go about pursuing this ambition, because I don't have the experience to figure it out yet. Although I relate more to Biff, I hope I can avoid the failure and disappointment that Biff causes his father and he feel.
