How does Montag attempt to seek happiness? What are some of the challenges he endures in order to attain this personal growth? What does he have to leave behind as a result?

Montag reassesses his life after Clarisse asks him the simple question, "Are you happy?" I think Montag looks for freedom which indirectly brings him joy. He looks for the freedom to read books and think: he looks for the freedom to distance himself from the spirit-crushing society that people are expected to be a part of.
