Scheduled our first product launch! How do you remember your first submission?

Just want to share this experience. The submission process was an interesting creative challenge, and after figuring it out and troubleshooting some problems, it just feels like a job well done and an overall productive day. Probably there will be some tweaks before the launch, but I'm also trying not to overthink it too much. Now it's time to prepare pre-launch and launch posts for social media :) And how do you remember your first submission?
