I think the wisest thing would be to start shadowing different docs across all specialties including the competitive specialties, NOW. This includes plastics, derm, ENT, ortho, optho, urology, rads, ER, radiation Oncology, and medical subspecialties like Cardiology and GI. Get a feel for what it's like to do their job. This way if you find something you like early you can persue this and be as competitive as possible. So, if you come to a point in 3rd year where you say, I don't want to do derm anymore, I want to do FP, you'll be sure there's a spot for you in FP. The reason it is important to try every field including the not so competitive ones, is that you cannot always predict swings in competitiveness or popularity. However for the forseable future the above listed specialties should remain competitive and I have a hunch that anesthesia will increase in popularity over the next five years, just how much remains to be seen.
