Early success is a terrible teacher. You’re essentially being rewarded for a lack of preparation, so when you find yourself in a situation where you must prepare, you can’t do it. You don’t know how.

Put simply, because many professionals are almost always successful at what they do, they rarely experience failure. And because they have rarely failed, they have never learned how to learn from failure.

Dr Burgelman, a famous Stanford business school professor said, it is far better to have understood why you failed than to be ignorant of why you succeeded.
