Starting a Blog

I have been thinking about starting a blog for several weeks now. There was just one problem. Most blogs are directed at one thing, saving money, making homes nicer for your family, gardening, crafting. So what should I blog about ? I have turned this question over and over in my mind.
I will blog about what is on my mind, when I blog ! So if you want to read on all kinds of subjects from someone with all kinds of interests, hang on while Sandra Sums it Up !
