A 74,200-note Second Brain, nine Obsidian crashes, one exact breaking point, and the decision that proved the system was finally useful.
Show Notes
Lennox's Second Brain holds 74,200 notes. On this Mac, Obsidian opened 44,331 of them. Note 44,332 crashed the graph.
This episode isn't a tour of a pretty knowledge system. It's the story of why Lennox built one after losing his mum, how perfectionism turned the graph into a new form of procrastination, and why nine crashes finally forced a simpler question: could the system help with a real decision?
The answer shows up in PR #122. Codex checked Lennox's notes, Slack and GitHub, caught that a proposed change would undo Samsam's live work, and stopped before the damage was done.
You'll hear the exact local test, the fix, the limits, and one practical check you can run this week. Ask your Second Brain a real question you need to decide. If it can't find the right notes and help you choose, stop feeding it. Make it useful first.
