Bias towards action. Act quickly to learn faster without being careless.
When I'm building products, I try to default to the smallest responsible step that gives me feedback with some guardrails so that mistakes are cheap to fix and have limited blast radius.
That's helped me ship to millions of users. I've seen a lot of people stall out on their ideas and its happened to me too. On side-projects, I would keep refining them long after they were good enough to try out - it just "needs one more feature", "to load one second faster" etc. But it's easier to reason about something once it’s real and people start using it.
The folks I've seen have the most impact often weren't the smartest in the room. They shipped something small, noticed what broke and shipped a better version as soon as possible. Being wrong early was part of how they learned. Meanwhile there were so many people waiting for certainty that just continued waiting and didn’t ship.
