"It's Important That You Don't Only Use Marshmallows"
That was my favorite sentence from this researcher, explaining the findings and lessons from the Marshmallow Game (which I looked up thanks to a weekend conversation with Stevie T), a test done of children ages 4 and 5 that turns out to be strongly predictive of academic success and higher psychological functioning. Apparently, it features prominently in a newish book called "The Time Paradox".
