I would say there isn't really a "need" to examine all the decisions, although Socrates did say: "The unexamined life is not worth living." There are plenty of people in the world that do not practice rigorous metacognition, planning, or reflection. In the modern mindset, romanticism seemingly reigns supreme. In plenty of people's minds, being carried away by passions is "true love." This isn't to say that either way is right or wrong, as many people have achieved happiness and what they call love through either path.
