Memo & Fractional Write Up - An Update & Apologies

It has been a very long time (I know, I know...). Writing became the sacrificial lamb to keep up with life lately, but I’m currently traveling in South America to unwind and finally have the breathing room to get back into it.In this video, I’m sharing a quick update on what's been eating my time, including an "AI feedback loop" I got stuck in while optimizing my workflow, and a sneak peek at a Global Logbook tool I'm building with a friend—inspired by Warren Buffett’s old-school Moody’s manual flip-throughs—to replace standard doom-scrolling with market screening. I also dive into the downward spiral of Mount Logan Capital ($MLCI), what I've learned from experts and executives about their insurance cash loops, and why it probably belonged in the "too hard" pile from the start.Read the full, detailed memo on Substack: https://andreevdan.substack.com/p/memo-and-fractional-write-up-an-updateSubscribe to the 18 Degree Journal: https://andreevdan.substack.com/Let me know in the comments if you have any feedback on the logbook tool, or which market we should flip through first.

MEMO - 100 Year Holding
