Blog or blip

I had wanted to write a book. I know that is a huge undertaking and who has that much to write about. My thinking was a book would be more private, so one would know who I was. I could use a pseudonym and have a fancy editor to do rewrites so it would not even sound like me. However, I don't know a publisher or an editor so here I am writing a blog. I didn't want a blog because it was so open so out there anyone could read my thoughts my life story and they want pictures ugh. So, I delayed. I thought taking so much personal out of it would it be long enough for a blog would it just be a blip? So, I decided it will get personal but not like a book under my secret name, and it will go into other people's lives that intertwine with mine but not so intimate.
