Goldilocks Tasks: a spectrum where the challenge is not too easy, not too hard, but just right for flow and mastery

Goldilocks tasks

The sweet spot for flow and mastery where the task is not too easy, not too hard — it’s just right.  Also, just the right spot for learning similar to Vygotsky’s zone of proximal development. In that model when you’re out of your comfort zone, and not in your anxiety zone you’re in the learning zone. And yet another way of looking at it, still without as catchy a name as Goldilocks tasks, is getting the right match of challenge to your skills to avoid anxiety and boredom to be in flow. I learned the name from Dan Pink’s excellent book Drive.

Stages of grief

This is an adapted version of the Kubler-Ross model for the stages of grief from her work with terminally ill patients. I should caveat that this is overly simplified in several respects and people don’t necessarily go through all these stages, nor necessarily in this order. Though, when you look at it, it’s hard not to have the feeling that it could provide some value in understanding that complex and difficult situation. I find it interesting as a more generally applicable model of how people deal with change. I think it’s possible to relate to some of these stages at some points in life which have experienced major change.

How to speak plainly illustrated by Owl-speak and Pooh-speak from Winnie-the-Pooh

How to speak plainly, by Pooh Bear

Winnie the Pooh teaches us how to speak plainly and avoid Owl Speak. There’s a surprising amount of wisdom in A. A. Milne’s classic stories of Winnie-the-Pooh. If you haven’t read them for a long time, you could do much worse than try them again. Owl Speak As one small example, I find there’s a lot of Owl Speak around as we get older, where we could all probably benefit from a dose of Pooh’s simplicity. Owl Speak includes never using a short, simple word when a long and complicated one would do. For example, in one revealing exchange, Owl explains: “Well, the customary procedure in such cases is as follows.” “What does Crustimoney Proseedcake mean?” said Pooh. …”It means, the Thing to Do.” says Owl. We learn more and more Owl Speak the more time we spend in school, only to have to work to remove it when we are older. All the Winnie-the-Pooh books are lovely to read: Winnie-the-Pooh, The House at Pooh Corner, When we Were Very Young, and Now we are Six. Both quotes are from The House at Pooh Corner. Or, if you prefer to have the wisdom called out, you could try The Tao of Pooh, by Benjamin Hoff. This sketch was updated for my book Big Ideas Little Pictures

The classic game theory dilemma where two prisoners are individually offered a deal if they’ll betray the other prisoner. But if they both betray each other then it’s bad news for both of them. What they choose depends on what they think the other will choose.
