Research (and life experience) suggest strongly that kids who get straight As in school may not actually have the best preparation for real life:
The evidence is clear: Academic excellence is not a strong predictor of career excellence. Across industries, research shows that the correlation between grades and job performance is modest in the first year after college and trivial within a handful of years. For example, at Google, once employees are two or three years out of college, their grades have no bearing on their performance. (Of course, it must be said that if you got D’s, you probably didn’t end up at Google.)
In a classic 1962 study, a team of psychologists tracked down America’s most creative architects and compared them with their technically skilled but less original peers. One of the factors that distinguished the creative architects was a record of spiky grades. “In college our creative architects earned about a B average,” Donald MacKinnon wrote. “In work and courses which caught their interest they could turn in an A performance, but in courses that failed to strike their imagination, they were quite willing to do no work at all.” They paid attention to their curiosity and prioritized activities that they found intrinsically motivating — which ultimately served them well in their careers.
Straight-A students also miss out socially. More time studying in the library means less time to start lifelong friendships, join new clubs or volunteer. I know from experience. I didn’t meet my 4.0 goal; I graduated with a 3.78. (This is the first time I’ve shared my G.P.A. since applying to graduate school 16 years ago. Really, no one cares.) Looking back, I don’t wish my grades had been higher. If I could do it over again, I’d study less. The hours I wasted memorizing the inner workings of the eye would have been better spent trying out improv comedy and having more midnight conversations about the meaning of life.
I've known all of this since first grade, when I realized that getting straight As would require me to do hundreds of pointless math problems every night for six months. Around that time I encountered the Terrible Trivium in The Phantom Tollbooth and the pieces fell into place. (For the record, I do arithmetic on paper just fine—and I also have Microsoft Excel to do it for me.)
