Takoffs are optional landings are eventually mandatory?

Go arounds are a NORMAL procedure that should be used routinely.
On approach consider it an approach to a go-around, the landing is optional.
Nice work, good decision Captain. Pucker factor x.x?
If more people would consider landing optional and the go-around and/or diversion more, there would be a whole lot less accidents. Such a simple little decision with significant positive impact on safety. What happened here was CRM, cockpit resource management. You listened and took action. Very nice. Even though your intended landing/flight was not completed, the flight was a total success (because you made this post). Even though you may have been in there before successfully, the co-pilot could've sensed some thing, not even he was totally aware of. The words "I'm not comfortable" is a red flag usually, sometimes not. Even if you had disregard the input, it at least deserves some serious discussion and analysis (not rationalization or got-ta-get-there-i-tus).
