In Spider-Man 2 (2004), Peter Parker gives up being Spider-Man at some point during the movie, because of certain things happening.
Later during the movie, he decides to pick up his Spider-Man responsibilities again, and while standing on a rooftop, getting ready to do his thing, he psyches himself up with the following words: "Strong focus on what I want".
So now what I don't understand is what is he referring to when he says that? Because what he really wants is Mary-Jane, but he can't have her because she will always be in danger of his enemies (a choice he himself made).
Actual question: What does Spider-Man want, other than Mary-Jane?
