Do you write down your worst-case scenarios before hitting publish?

Launching something new always brings a weird wave of doubt right before it goes live. I started a habit a while ago of just dumping every worst case thought onto a blank sheet of paper like what if the server crashes or what if nobody even notices.

Once it’s written down it somehow stops feeling like this massive invisible monster in my head. Most of the time the things I'm stressing about never even happen.

Do you have any little mental tricks or habits to calm your nerves right before a public launch?
