Like you, there are parts of the job that I hate. There are parts which have a "take it or leave it" feel. There are parts that I love.
The OR is the same way. There are some surgeries that I LOVE to do - myomectomies, laparoscopic hysterectomies - and some that I hate (vaginal hysterectomies, post-partum tubal ligations - both usually involve much swearing out of my mouth).
I still haven't figured out what exactly makes a surgery fun versus routine versus "I hate doing these!". But like porn, I know it when I see it.
