When Willy asks Bernard, “What- what's the secret?” What secret was he asking about?

Willy was asking Bernard how he was able to manage his life well while his son, Biff, wasn't able to catch on in life like Bernard did although he used to be a "football star." For example, Biff's life seemed to have ended after the "Ebbet's Field Game." After flunking in Math, he didn't become interested in graduating anymore.

Reality speaking, Willy was actually asking where he has gone wrong as a father.

Explanation:

The question above is related to the story entitled, "Death of a Salesman." It focuses on "Willy Loman," a salesman, and his disappointments in life. Willy wanted Biff, his elder son, to be a successful person because he had the potential in life. However, he dropped out of school and couldn't fulfill his dad's wishes. On the contrary, Bernard, the son of Charles, who used to be a nerd when he was young, became a lawyer and had a wonderful family.
