I agree that laid back can't mean lazy...and that is a fine line. I'm afraid the 80 hour workweek is somehow making people think that surgery is more lifestyle oriented now, but it is not - 80 hours x 5 years can still consume quite a bit of your life. No other residency specialty really works 80 hours x 5 years like we do - others may have some busy months, some easy, but surgery residents rarely have easy weeks even.
You need to be committed to learning the craft, taking care of your patients well, always taking every learning opportunity to do something, even if its 3 am when you get called for that central line consult - you are happy to have the opportunity to practice another procedure. If this is not you, general surgery is not for you.
You don't have to have desires to be a dept chairman or anything - we need the small town community surgeons maybe even more than academic powerhouses...but we need all surgeons to be committed to thier work to a certain degree b/c people's lives are in their hands. Its a real honor to train in surgery, but it's a real committment too.
