It's all hardwork behind a great presentation

Finally I got a chance to read this article recommended from Guy Kawasaki's blog. A great article described all the hard works behind Steve Jobs Keynote address at the beginning of the year.

Looking back, though I got a pretty good grade on my first speech in my public speacking class, I'm not satisfied. After reading the Guardian article and the tips and advice from Kawasaki, I know what to work on.
