The author discusses three common types of people who struggle in dating: the romanticizer, the maximizer, and the hesitator. The romanticizer has unrealistic expectations of relationships, believing in a soulmate mindset where love should feel effortless. The maximizer has unrealistic expectations of their partner, always seeking someone slightly better. The hesitator is not dating because they feel they are not yet perfect, waiting for a future moment when they will be ready.
