I have discussed my career ideas with a doctor who has been a mentor and counsellor to me for a good while, and she thinks that I am on the right path with regards to personality and lifestyle fit with my main plans.
Of course, I have to decide for myself, but it is nice to hear an opinion from somebody who knows me and my weaknesses and strengths fairly well, and who also has a good understanding of the medical specialties and what is required for them.
Ideally it would be nice if everybody had this kind of guidance. Luckily (in Australia) we also have several years in which to decide what we want to do, and it is common to change career paths. I think this is one of the great advantages of medicine - you are all medical doctors, but there is a career path for nearly every personality. :)
