Lifes Like That

How many blogs are too many??  Does it all depend on the individual and how creative they are or how much time they have on their hands.  Currently I run and maintain six blogs.  And, some days I find that is just too much.  To try to discuss relevant content on them each and everyday can get quite tiresome so I wonder how everyone else does it.  In one of the forums that I frequent, I have seen people who have 13 or 14 blogs and even one person who claims to have 20.  How in the world do these people do it?  Do they spend their entire day on their blogs and where do they find all the inspiration needed to continue to write on these many blogs.

If your a blog owner yourself, how many do you run?  Where do you find the time to maintain them all and where do you get your inspiration for what you blog about?
