I have a friend, a fellow Indie author who has spend the last couple of weeks preparing for a cover reveal. She has been so excited. I really wish I had the same excitement level with my book. They just sent me the previews, I picked one, and that was it. A total washout from my point of view now. I had no clue then, so it didn't bother me.
I have a really cool original cover and wish I had used it to help with the promotion of my book. Instead I did everything backwards. I am still trying to play catch up on a lot of the promotions of my book. My publisher also did not tell me that many sites will not promote a book once it is acutally published. Bummer Man!
So don't do what I did and rush through publication. Use your cover for publicity. Build anticipation for your book with a cover reveal. Enjoy every moment you can with your book. All this only happens once. Happy Trails To You!
