Hello, I am a mom in her late 30's.  I have a blog called The Self Help Mom at http://www.theselfhelpmom.blogspot.com.  I would also like to make a blog about everything.  I guess what I mean is a blog about everything from personal, diet and fitness, recipes, daily happening and really just discuss everything and anything you could talk about.  I was wondering if that is something that you can do with a blog?  Can you blog about all those topics or do you have to stay with 1 niche in particular.  Thanks for any help you could give me.  Have a great weekend!
