Eye queue

This comment by "Cabochon1360" on one of David Mitchell's Youtube videos struck me today (far more than the video), and sums up my own feelings better than I could have.

In my teens, I was proud of my allegedly high IQ. But decades of failures and other humbling experiences have shown me it's just one personal characteristic, and not the most important one.

Another thing to bear in mind is that telling your kids they did well on a test because they're smart hinders their future performance. Perhaps counter-intuitive but it's been demonstrated in a number of studies (even when performed on adults, AFAIK).
