Do you know how many hours it takes to write and launch a book?

I remembered a rule that says you have to spend 10,000 hours doing something to master it, or to hit the point of excellence... I read that somewhere.

Writing a book of 300 pages will be variable from one person to another, and I am only sharing my own experience:

- First draft: 120-130 hours

- Second draft: 40-50 hours

- Self Editing: 30 hours

- Review after editor: 40-50 hours

Then we have to add the process of launching and advertising which is an ongoing process in the beginning before it becomes automated.

Overall, I would estimate a 500 hour work dedicated for one book writing and launching.
