While in Omaha at the Berkshire Hathaway Annual Meeting, I got into a long conversation with a friend and mentor on one particularly impressive facet of the show: The effortless air about Buffett and Munger's entire performance, the ease and elegance with which they operate in what looks like a pressure-packed situation.
The term sprezzatura has come to be defined as a "studied carelessness" in the modern English language. I think of it as earned effortlessness.
The Paradox of Effort: You have to put in more effort to make something appear effortless. Effortless, elegant performances are often just the result of a large volume of effortful, gritty practice. Small things become big things. Simple is not simple.
