We've become so used to the concept as a measuring and sorting tool, that it and its correlates - below-average, above-average - are everyday speech. We don't even question the language, although the challenges we face require a different mindset.

I care deeply about opportunity and fairness, because I grew up really poor.

Talent - really, everyone agrees, it's multidimensional, and often overlooked in standard assessments. That's not hard for people to accept.

I enrolled at a local college, but this time paid attention to myself - took only courses that really interested me, even if they weren't in sequence; kept out of classes with people I knew from high school, because I tended to act like the class clown around them; selected teachers by their teaching style - until I could build up my study habits. I ended up graduating with a 3.97 GPA and got into Harvard for my doctorate.

Character is incredibly jagged, and incredibly contextualized, even to the point where I still feel uncomfortable thinking about it.

Education and the workforce: I think these two things go together in terms of human potential.

Growing up in rural Utah had a lot of benefits, but in an environment that prized conformity, fit wasn't one of them. I ended up in my senior year with a 0.9 GPA, which I think you actually have to work pretty hard to get. In the exact same month they kicked me out of school, my girlfriend - still my wife today - told me she was pregnant. So, it was an interesting start to life: working 10 or 12 minimum-wage jobs; getting bored really quickly and quitting; having my in-laws - rightly - in full panic mode and thinking I had some kind of character flaw.
