Start with a single goal for the whole meetup, then break it into three chunks: set‑up, main activity, wrap‑up. Give each chunk a fixed time slot and stick to it. Put a 5‑minute buffer between slots for overruns. Assign one person to run each block so no one is juggling. Use a paper list or a simple digital calendar, no fancy tools. Review the plan at the start, then keep it quiet and focused. That’s all you need to keep things low‑chaos and high‑impact.
