How can one define happiness? It totally depends on the priorities an individual has set for himself/herself. For example, for you to become a Neurosurgeon and work in the US might bring happiness but for someone graduating from a College without any student loan might bring happiness. So it depends on each individuals perception of happiness. Neurosurgeons in the US have access to a variety of Medical Conditions than compared to India because of the Research facilities available. Neurosurgeons in the US put atleast 40 hours per week. The life is past paced and can be quite stressful but if you like your job, there is nothing that can stop you from being happy. Because Neurology is an important field of medicine, Neurosurgeons have to be on their feet all the time for any aneurysms or tumors to be treated. Patients choose their doctors and so if you are good at what you do, are empathetic towards patients and their families and work with diligence, Neurosurgery might make you happy anywhere be it in India or abroad.
