Be careful painting with broad strokes that surgery is all puppy dogs and ice cream, especially based on a shadowing experience. The field has come a long way from some of the stereotypes of the past, but it is definitely still very "hard-assed" compared to many medical specialties. There's a certain warrior mentality to the field fostered by the grueling hours. It's less "mean" than in the past but still more rigidly hierarchical and there's less tolerance of imperfection. There's definitely a certain "personality" to the field. Of course there's exceptions to every rule and there's plenty of examples of attending surgeons who don't fit the typical surgeon bill, but the majority of the field still acts and thinks a certain way and if you can't enjoy interacting with that type of personality on a daily basis it can make life miserable. You won't be exposed to many of the nuances of the field until you rotate through as a MS3 (which is why I find this survey interesting)
It's a very polarizing field. People typically either revel in it or get worn down by it. Love it or hate it sort of thing. It's easy to become enamored with the idea of surgery, another thing to still have a grin on your face when you haven't had a day off in 2 weeks, are running on 3 hours of sleep, and are scrubbed on a 5 hour case. Just 2 cents from someone who's actually masochistic enough to consider going into the field.
