A long-term friend and ex-colleague – now retired from finance – recently sent an email to me and a few mutual workmates from the old days. His message? He had just applied a golden rule that he (and we) used to use in our days on the trading floor to solve a problem totally disconnected from trading or derivatives.
“It’s amazing how often lessons from finance help in real life,” I wrote back.
And of course, that got me thinking: what lessons from a career in finance do I still use?
