"The Effort Effect"

An article I got from Eran:
How to Change the World: "The Effort Effect"
I'm not sure if it's too simplistic, but it's an interesting idea.
I found the last 2 paragraphs the most useful/new for me...
I was skeptic about applying the theory (which is about kids) to employees (who are adults), because adults, perhaps, are less likely to change thier 'mind-sets' and their employers are not necessarily those who can/should educate them (as parents).
