This model was created Dr. Ron Westrum, a widely-cited sociologist who studied the impact of culture on safety

Thanks to Dr. @nicolefv, I was able to interview him for an upcoming episode of the Idealcast! 🤯
It was a very heady experience, and while preparing to interview him, I was startled to discover how much work he's done in healthcare, aviation, spaceflight, but also innovation.
I've read 4+ of his papers, so I thought I was familiar with his work. (Here's one paper: https://t.co/7X00O67VgS)
I was startled to learn he has also studied in depth what enables innovation. He wrote a wonderful book "Sidewinder: Creative Missile Development at China Lake"

Dr. Westrum writes about China Lake Research Labs: "its design and structure had one purpose: to foster technical creativity. It did; China Lake operated far outside the normal envelope... Sidewinder & others were "impossible" accomplishments,
I love this book because it describes traits of organizations that routinely create and maintain greatness: US space program (Mercury, Gemini, Apollo), US Naval Reactors, Toyota, Team of Teams, Tesla, the tech giants (Amazon, Google, Netflix, Google)

[A quick thread]

So yesterday I sold two of my holdings that I didn't like very much for the following
Risk reduction in the case of DataDog. I have too many holdings in a similar space. GoodRx's business model doesn't entice me as much as I would like it to. Ultimately, it was to free up some cash in the event that a significant dip comes along. I like to keep 10% in free cash.

I know what you thinking: "smart move! 😎"
Will I be going on a buying frenzy today? Not quite. I think I'll sit today out. I've had some great lessons about the dip that I'd like to share with you.
I came across this fortune teller on YouTube who could predict pullbacks.
If this guy is anything to go by, we may have a sale on our hands next week. Do you have:
