TLDR

Lenny Rachitsky says his newsletter grew from a sequence of signals: one Medium post, a friend’s advice, and nine months of weekly publishing.
He ties creative output to lived experience, saying the strongest posts and Michelle Rial’s charts come from doing the thing before explaining it.

Key Takeaways

Lenny says the newsletter became viable when the paywall worked and started producing meaningful dollars about a month after launch.
He still sees weekly newsletter and podcast publishing as a treadmill, but says he cannot imagine a more fulfilling job.
Michelle Rial says the best charts come from iteration, real parenting experience, and simplifying ideas into visual forms.
Both frame product management as influence, judgment, and communication, not just project management.

Notes

Lenny says he left Airbnb after seven years with four paths in mind: start a company, join a startup as first PM, join a big company as PM, or advise companies.
His first widely shared post was about what he learned at Airbnb; Medium featured it and Branches shared it internally.
Lee Jacobs, now a VC, pushed him to keep writing because he enjoyed it and readers valued it, which is rare overlap.
He moved to Substack, committed to weekly publishing, and after nine months concluded he could likely do another nine months.
The Lindy effect helped him justify the paywall: if something has lasted nine months, it may last another year.
COVID and the possibility that Airbnb stock would not rescue him made making money from the newsletter feel urgent.
He says the job is deeply fulfilling but also relentless, because each finished post immediately becomes next week’s problem.
His long-term uncertainty is what happens when he can no longer ship every week, since the Substack writer plus podcast model depends on consistency.
He estimates his stress level is lower than average, partly genetic and partly due to deliberately not taking things too seriously.
His stress tools include meditation, breathing, exercise, and a University of Pennsylvania happiness course that raised his baseline optimism.
A Joshua Tree trip with psychedelics during the newsletter’s early phase gave him the confidence that he had wisdom to share.
Michelle says charts need the right amount of coffee, a deadline, a good night of sleep, and a physical way to turn thoughts into simple visuals.
