Feeling Overwhelmed. Making a List.

Hi all, I'm planning to publish my first book in June, and I've been doing a lot of research/planning. I've gotten a lot of good information, and I'm trying to take things step by step because I was feeling overwhelmed. I've made a check list, but it feels a but chaotic and disorganized. I noticed the check list in the sidebar no longer works. Does anyone have a good list they work off of when publishing? Or would you mind adding to mine?

I've got the basics like -

• Copy edit/Proofread
• Formatting (both ebook and print)
• Cover
• Blurb/Synopsis/Selling Paragraph/Call to Action
• Copyright
• Finding Metadata/Keywords
• Front/Back Matter
• Website and/or Substack/Patreon and/or Discord
• Author Photo
• Mailing Lists
• Socials
• Marketing Plan

I've already checked off a lot of these things, and my list has a lot more notes/timelines/details, but I'm worried I'm going to forget or miss something. If you have anything to add, please let me know! Or if you have a go to check list somewhere, I'd love a link!
