Through Christine Kane's blog I was made aware of a speech that J.K.Rowling presented at Harvard this year, it was posted on YouTube by another. I found that Rowling did very well to outline the benefits of imagination and contribution.
So I thought I would share this find with the people of this forum, just as someone shared it with Christine. The video is split up into two parts, here's a link to the first of the two parts. I found it to be a great source of inspiration, you might too.

Character & Contribution appeared to be the appropriate forum category for this at the time.
