Hello!!
if we seek into earning prospective orthopedic surgery is the highest paying specification of India,after that it's cardiology,to be more successful you can be a cardiologist or neurologist even a gynecologist but you will have to be champion in your stream.
But ,Every branch has it's own importance ,it would be better to ask yourself which branch would suit you.
If you gain deep knowledge in any branch that would make you famous among the patients.


Thank you
