You may have noticed that Sethi used the cool tool called Prezi. Prezi can be used in many way; in this case Sethi used it smoothly in a linear fashion as text would enter in perfect sync with her narrative and videos played on cue. Note that she didn't stand behind a lectern, turn around or fumble around with the technology. The technology was there and it helped her talk, but it did not become a barrier. Her message and delivery were wonderful.
Shukla Bose: Teaching one child at a time
This is another inspiring talk below. Shukla Bose does not use slides except to bring in video clips from time to time; mainly it is her and her story, front and center and delivered with passion and an infectious optimism. She's doing such good, important work. It's important for leaders like this to be able to stand and tell their story, and she does it very well.
