1) The speaker makes a fun and intriguing promise to the audience right at the beginning of the talk, which is great for hooking attention. Importantly, there is a genuine pay off to this in in an excellently managed audience interaction section later in the talk. 

2) Great pacing, including pauses that allow the audience to absorb her points.

3) She shares her own personal story in a highly relevant, succinct and compelling way. It provides a perfect amount of context before linking back out to the wider context of her research. Impressively done. 

I also really enjoyed Jane McGonigal’s book ‘Super Better’, which expands on the ideas in the talk. Gamifying growth is definitely applicable to all of us speakers.

Have fun!
