“I'm very used to like iterative building and kind of this idea that you never actually finish anything... this whole idea of like it's a bit like I guess like making a movie where once it's done it's done”

Match shipping cadence to the medium

Book publishing is the inverse of SaaS — no A/B tests, no iteration, no immediate feedback loop. Budget for a multi-year process you can't tweak post-launch, and accept that the audience will be unpredictably broad. If you need the dopamine of weekly shipping, books will frustrate you. Pick the right cadence per medium instead of fighting it.
