What to blog about?

I have been blogging for about 4 years and almost the whole time I have wondered what to blog about. I mean I have a variety of tastes and interests. I'm an author, college professor, and business woman. I'm a mother, an ex-wife, a girlfriend, and a friend. I like fashion, reality TV, music, and wine. That's just to name a few. So I have struggled with trying to decide who I "mostly" was so that I could have this narrow focus for my blog. I've not been able to figure that out in four years but what I finally did figure out is I just needed to blog about what inspired me and if that changed from day to do so be it. None of us are one dimensional people. We all have a variety of interests which is what makes us the amazing people we are. So my blog will be about me, what I like, what I don't like, just what I'm moved by. I will write for myself and just hope others find it remotely interesting and possibly entertaining. If not I am ok with that. I think what matters most in the choices we make in life is we make choices for the right reasons. Not because we feel we should or because someone told us too but because we know it's what right. That's logic you can't argue with. Or can you? How do you decide what to blog about?
