Names and Titles

This blog has nothing to do with my novels. I just wanted to write about this topic because I might change the name on one of my books, which led me to think about my name changes.
I've changed my name a couple of times over the years. I'm 82, so that's not a lot. Although, most people have the same name forever. I was named after my dad's two sisters and my name was never pronounced correctly (according to me). And I wanted my own name, now theirs.
I had issues with my dad, so when he died in 1966, I was 24 at the time, I changed my last name to my step-fathers. Several years later, 1983, I changed my first name. Now, because of the damned drivers license needing to be something special. Well, let me share how I went about the name change the other two times. Every year for five years, I filed my taxes under my new name with my birth name in parenthesis. The government didn't object.
Now I almost need to change it again because of the licensing laws, because my birth certificate has my birth name on it, not my new name. Well, it's not new to me but you get the idea. If I go down to the Dept. of Licensing with my current birth certificate will they laugh me out of the building? When I got my driver's license I lived in Oregon and it had my birth name, so there's a record, somewhere, or so I hope. If I can convince them, I won't have to pay $269 for a name change. Ouch!
Changing the title on a book is easier. I create a new cover and put a new title on and voila, it's done. I do have to unpublish the other version of course. I wish my license was that simple. Sigh...
I'm thinking of changing the title on a couple of books because so-called experts say if it's not selling then change the name, or a dozen other things you can do different. I'm tired of it. Leave to the Lord, some say, but when nothing changes, nothing changes. What to do?
