Is consistency key?

19th-century philosophers Ralph Waldo Emerson famously said, 

"Consistency is the hobgoblin of little minds." 

Bezos apparently agrees that consistency is overrated.

Bezos -

 “the smartest people are constantly revising their understanding, reconsidering a problem they thought they'd already solved. They're open to new points of view, new information, new ideas, contradictions, and challenges to their own way of thinking," 

That willingness to consider new information goes hand in hand with a willingness to admit your old way of thinking was flawed. 

In other words, to be super smart you have to change your mind a lot. 

Do you agree?
