Answer: Desiring this man’s art, and that man’s scope.
In Sonnet 29, Shakespeare presents a character who complains about his failures in life. He believes he has become an outcast, and he envies the things that others have. This is shown in the line “… Desiring this man’s art, and that man’s scope…” However, the speaker then remembers that he still has his beloved. This fills his heart with joy, and makes him realize that, in fact, he has a lot, and he would not trade it for anything else.
