Any tips for the day before launch?

Full of excitement! When I read a post by @anar_hagverdiyev asking if it is possible to sleep before the launch, I didn't think it would be possible for me to lose sleep. Now, however, the adrenaline rush seems to work. I am all into making our data better, reaching out to more people, asking for tips from them, editing our graphics, etc. I have learned a lot in a single day today about launching because of the anxiety/excitement. However, I would be very grateful if you could provide some tips on the launch. What did you learn from launching your product on Product Hunt?
