Jonah Lehrer: it's important to find "the upside of error"

Jonah Lehrer takes up our favorite subject in his Wall Street Journal Saturday column ("The Art of Failing Successfully"). He refers to the work of Carol Dweck (of course), and includes this nugget:

The psychologist David Nussbaum has shown that whether we tend to learn from mistakes or brush them aside, the response is rooted in repairing our self-esteem. Failure is never fun, but success requires that we learn to fight through our frustration and find the upside of error.

Lehrer also refers to this Bob Dylan song that contains the lyric, "there's no success like failure, and failure's no success at all." Enigmatic, just like its creator!
