"There's nothing more annoying than cold logic and reason when you've got a good fit going," is a quote from James Patterson's book The Angel Experiment. It highlights how sometimes, strictly relying on logic can undermine natural chemistry or intuition in a situation or relationship.
The quote emphasizes the idea that emotional connections and instincts often matter more than pure rational thought. It suggests that over-analyzing or prioritizing logic can interfere with and potentially ruin genuine bonds or moments that feel right on a more instinctive level.
