She seems like a really nice and smart lady, and this is a topic I'm really curious about and want to get better at, but her speech/presentation itself didn't work for me at all. Completely failed to grab my attention, I started speeding up the video, and then skimming, and finally ran out of patience and closed it without having learned anything new.

Getting to the point quickly, skipping to the most valuable and insightful points, and talking in such a way that grabs people's attention and gets them excited to hear what you have to say are essential public speaking skills, but very hard to learn.

The most captivating public speakers can speak with cadence and energy that makes every sentence entertaining, makes it impossible to stop listening (for great examples, see Max Landis' Superman pitches on youtube, or Dan Harmon's Harmontown podcast, or any good stand up comedian).

I really wish I could learn to do THAT.
