What is confidence????

A hypothetical situation where 20 CEOs board an airplane and are told
that the flight that they are about to take is the first-ever to feature
pilotless technology: It is an uncrewed aircraft. Each one of the CEOs
is then told, privately, that their company's software is running the
aircraft's automatic pilot system. Nineteen of the CEOs promptly leave
the aircraft, each offering a different type of excuse.

One CEO alone remains on board the jet, seeming very calm indeed. Asked
why he is so confident in this first uncrewed flight, he replies : "If it is
the same software that runs my company's IT systems, this plane won't
even take off." !!!!

That is called Confidence!!!
