First-time Maker launching Streeboard on Sept 7th. What's the biggest mistake to avoid?

Hi everyone! 👋

I just scheduled my very first launch for Streeboard (an optimized daily routing tool for travel spots). Since I am exactly 14 days away from the big day, I want to make sure I'm doing things right.

For those who have launched successfully before: what is the single biggest mistake I should avoid during these next two weeks? 

Looking forward to hearing your thoughts and connecting with fellow builders here! 🚀
