I recently blogged a new study by economist Henry Levin about the crucial importance of non-cognitive skills.

What matters most? Persistence, motivation, reliability, team work, the ability to work well with others, communication skills.

Levin cites Nobelist James Heckman, who said that parents read “The Tortoise and the Hare” and “The Little Engine That Could” to teach these lessons to their children.

How many really smart people fail in life because they lacked persistence and motivation?
