Hey Christine!
I agree with the above. And actually, I have the same goal as you do. I've written the VERY rough draft of a novel and I would like to maybe revise it (a LOT) and publish it or write a different novel later on that I will publish. But writing isn't something I'm sure I want to make a career of. It's just something I love doing, and if it pans out, great. If not, I have other things I love to do as well.
So, to make a long answer short...No. I don't think it's weird at all, but it does relate to your life!
