As a MS1, I am in constant flux about which residency programs to aim for. However, by the middle of my second year, I at least want to be "aiming" somewhere. Can anyone look into their crystal ball and predict which residencies will be attractive, competitive, worthless, etc. 2/3 years down the road? I know that I should seek what interests me most (yada, yada, yada) but lifestyle is an important issue. For those of you in a residency now, what may you have done different, if anything? I know this is somewhat ambiguous, but I am looking for some real generalized answers.
