I went to medical school to learn how to help people through the practice of medicine. My pre-clinical years did nothing toward that end. It was another stepping stone toward my MD, but it functionally did not prepare me for any aspect of practicing medicine. The little relavent information that was picked up was largely lost in the volume of unimportant schooling or repeated ad nauseum later on when it was relavent. From my perspective, there is a purpose to pre-clinical learning, but as it was applied at my medical school (and from others at their medical schools), it failed miserably.
I hated my pre-med curriculum for the same reason. I had no problem working 40+ hours a week in the lab during the semester or 80+ during the summer or taking 20+ credits. But, spending time in a class for the sake of taking a class was torture. I assume based on your commentary that this doesn't really bother you that much. You disliked the time commitment and got exausted on your Surgery and OB/Gyn MS3 rotations. I have enjoyed my residency despite having a much much higher time and responsibility commitment than an MS3 rotation. Yes, patients ask if I ever go home. And I honestly tell them that if I didn't enjoy being there working as hard as I am, I wouldn't. Different strokes for different folks. You went into Derm. I went into Vascular Surgery. I think we both went into the fields that fit what we like and stayed away from what we don't like. I'd say thats good for both of us 🙂 and lets both be thankful that #1 both types of jobs exist and #2 we ended up in the right ones!
