I did, like most young surgeons, practice tying surgical knots. You know, you take some string to your room at night, and you practice tying knots with one hand, or your left hand, and doing that sort of thing. And just thinking about surgery. And, you know, practicing. Get a scalpel, and practice just, say, cutting a piece of meat or something like that. You sort of learn how you want to hold your fingers, and that sort of thing, and try to become graceful when you operate. Because it’s sort of that gracefulness and poise at the operating table that inspires others to think that you are an accomplished surgeon. I watched a number of surgeons in this country and abroad, and tried to see what it was about their technique that made them successful, and made them masters of the art.
