I found this quote in the comments on Gretchen Rubin's blog post Why I Don't Read Reviews of My Books or Profiles of Myself:
"...we all have to find what allows us to stay proactive."
Except I read it as "productive." It is very hard to write and put it out there. Criticism is inevitable. Even one negative comment can haunt and change you.
I'm not sure my book will make it to publication, but I remind myself that my job is to keep writing and improving. If I am successful, eventually, it doesn't matter who likes my book or not, as long as I find some who do. My goal is not everyone, but enough.
I decided tonight not to read reviews or information about myself online, if things come to that.
