I think an equally interesting question to ask would be: What are the specialities you have decided you are definitely not going to do?
I have a pretty big list lol
They include:
Paediatrics - because I can't deal with children.
Psychiatry - because they say you often end up like your patients
Dermatology - because it doesn't seem very interesting
General Surgery (Abdominal, Vascular etc) - because firstly, I dislike them greatly and secondly because their surgery is SO boring, its just plumbing and drilling.
and many more.
