You don’t need to be a celebrity.
You don’t need a blog as your megaphone.
You don’t need to be asked.
Has a book made a difference in your life?
Forget the essay. Say how it made you feel. Why does the book work for you?
There are places to speak up. Speak out. The author (or book’s) Facebook page. A website. Amazon.com. Goodreads. One sentences can move mountains. Or a sales meter, at least.
This isn’t to make the author obliged to you. This isn’t about having a personal interaction with the author. This is about being the one voice saying, “Yes, it’s good. Wait until you see how it makes you feel!”
Why post that blurb?
Because you’ll be creating, too, finishing a project soon. You’ll want someone to notice your work, to feel something over what you made yourself.
Karma keeps score.
