This is a great idea! It's very timely, I think my kids will really like it. I took the idea of using the Stanford speech, as well as sungadio's ppt, and the article from breakingnewsenglish.com to make a 50 minute lesson with a focus on goals, inspiration and accomplishments.
Here is the slightly revised ppt (for the worksheet), the worksheet and the lesson plan. I'll be trying it this week with a group of relatively low grade 1 high school students - it may seem a little ambitious, but I think with support from the teachers they'll enjoy this, and hopefully get a lot out of it

.
Thanks again for the great ideas!
