5K a month possible?

Over the last month or so I have looked into blogging programs that tout the fact their creators made 5K or more in income per month. I tried a 7 day trial at one place and I purchased two other blogging to 5K a month guides and what I have learned is that those who claim to make 5K a month by blogging have MANY blogs. One membership site I was a part of on a trial was created by somebody who has 40 blogs. Well that's how its done! You need to go register domains and more domains and set up WP blogs and then get affiliate programs all over those blogs.
I am sure many successful bloggers make 5K or more a month with just one blog, but the average person can not do that.

I have ten blogs, some have been out there a few years, most I started in the last year and I am still working on them. I am not making a lot of money, but I am enjoying working on them and promoting them.

The bulk of my income comes from PLR and resale software/ebooks.
