How many post does a average blogger have

The Question is how many post do i need to post a day or month or even a year? Well there is a few websites that i have red recently where i wanted to know how many post must a post a day, i did not really got the answer that i was looking for, but there is this one book i red a few days ago that said this guy makes a living out of blogging , and there was one time he worked 12 hours and posted 50 posts a day on his blog, so i think that is probably the answer i was looking for, so if you were wondering how many blogs you must post a day, especially if its a new blog, then i would say maybe 10 a day should be enough if you have the time.
