Hey, if you don't "get it," there isn't much I can do to persuade you that it is worth your approval. However, I will go ahead and paraphrase the speaker and attempt to interpret it for digestion in our context:

The WHY is more important than the WHAT. The human brain works in a way that the WHY is more at the core of what motivates each of us. Focus on the WHAT should be secondary to the WHY a person or organization does what they do, and the speaker points out that he has observed this commonality in successful people and organizations.

I see it being relevant here and in regard to Monero because the Devs focus first on WHY Monero is important and useful. That drives them to work hard on making it work well.
Also, the Adoption Curve or what Sinek refers to as the "Law of Diffusion of Innovation" is VERY relevant to Monero.

If you watch the video, the part where Sinek mentions that the Early Majority will never try something new until the Early Adopters have tried it and reported back that It Is Good. Because, he says, they will at first say "We don't like it, we don't need it, and frankly, you are scaring us."       
THAT IS HOW THE MAJORITY OF PEOPLE ARE WITH ANYTHING NEW. That's the complete lack of response that I got when I posted on my FB wall about MyMonero a few months back.
IMHO, the concepts Sinek talks about are relevant to ANYTHING, be it flatscreens or a cryptocurrency.
