In one form or another, I've discussed the subjects of motivation and the willingness to practice correctly several times on my blog. Most people who contact me about learning Pose lack one or both of these attributes. Anyway, as a follow-up to my post, There Are No Shortcuts, I found this post on the Freakonomics blog very interesting.
"So, do we need motivation to learn? Definitely. But alone it is insufficient. Deliberate (intelligent) practice plus motivation are together necessary and sufficient." - From Freakonomics - To Develop Expertise, Motivation is Necessary but Insufficient by Sanjoy Mahajan.
