I think mistakes are the essence of science and law. It's impossible to conceive of either scientific progress or legal progress without understanding the important role of being wrong and of mistakes.
And whenever I'm in a situation where I'm wearing the same as 600 other people and doing the same thing as 600 other people, looking back, I always found ways to make myself different, whether it be having a red lining inside of my jacket, having red shoes, it hasn't changed.
