You Can't Learn From Mistakes If You Refuse to See Them

 

"Good learners used the feedback not only to check their past performance, but also to adjust their next performance accordingly."

The ability to observe, absorb and adapt is a cognitive one.  It requires mental flexibility, the willingness to accept that maybe, your existing approach isn't correct, that you have something to learn.

 

Those who are so utterly confident that they hold the corner on truth, frankly, are delusional.

 

Everything gives, in time - and that which can't adapt doesn't survive.  That's what evolution is all about.
