Passage Summary: Being smart about your happiness is different from just doing what you want, because wants are usually impulsive and some 'wants'—like compulsions—don't actually make you happy at all.

Reasoning: Rational happiness requires long-term planning, whereas desires are typically short-term; furthermore, compulsions are a subset of desires that fail to produce happiness even when satisfied.

Analysis: In a 'Must be False' scenario, we need to find a statement that directly contradicts the rules established by the philosopher. The stimulus creates a clear distinction: ordinary desires provide at least a moment of happiness, but compulsions provide none. If an answer choice describes a person who achieves happiness through a compulsion, that would violate the premises. Similarly, since rational happiness requires long-term consideration, any claim that a purely short-term, impulsive act constitutes the 'rational pursuit of happiness' would also be a candidate for being false.
