The Day Before Launch

Ok, we're almost there. Thanks to the amazing PH Community, I've been able to gather a great deal of useful tips and could not be more grateful. Now, how to calm my nerves? I expect tomorrow to be fun but also quite tense. If you could go back, is there anything you would do differently? What are the activities you've done in the 🕓24 hours prior to the launch 🕓? (It sounds like one of those TV show flashbacks "24 hours ago" 😆)
