EnRon created a culture that worshipped talent, thereby forcing its employees to look and act extraordinarily talented. Basically, it forced them into the fixed mindset -with the fixed mindset, people do not admit and correct.
Which companies were great and how did they become great?
"The type of leader in every case led the company into greatness.
They were self effacing people who constantly asked questions and have the ability to confront the most brutal answers. To look failures in the face, even their own, while maintaining faith that they would succeed in the end - not constantly trying to prove they're better than others , they don't highlight the hierarchy, they don't claim credit for the work other people do and they do not mind other people feeling powerful .
They're constantly trying to improve, look squarely at their own mistakes and deficiencies"
Leaders are important and can improve their efficacy by being in the growth mindset. Try it.
