This lecture is a bit more dense in practical content, so some people like me, need more time to watch fully again and digest before echoing in a chamber :)
What I liked about her lecture is that unlike the previous ones that were full of general ideas about starting a startup, she related her practical advice to her own experiences and the mistakes she made. Examples are very useful and for me they ingrain the underlying ideas to a greater extent. Also learning about what not to do is just as, if not more important (see PG's lecture of counterintuitive parts of startups) than learning about what to do.
