A friend of mine left his corporate job a couple of years ago to pursue "a revolutionary idea", as he called it.
"What is it that you are are working on," I inquired, never once assuming this benign question would cause him to get fidgety.
He responded with a vague topic. Many months later he told me, “I didn’t want to tell anyone about my idea for fear that someone would steal it – too bad this made me sound really cryptic and weird at cocktail parties.”
