Creativity.

I feel that as I've gotten older and busier with life and all the drudgery that it entails, I've become less creative. I've never been an "artistic" person or had any real artsy talents. I don't paint or play an instrument. I'm pretty analytical, and super practical. I feel out of touch with my....imaginative side? Is there a way to reconnect with whatever creativity that I might have? Is this a common problem. I feel that I used to have a richer more imaginative inner life. I don't know if that makes sense. Now I just sort of work, engage in passive recreation, survive, etc. Something is missing. How does a person solve this. I thought I might try journaling although I have no idea how to do such a thing. I like to write. I write for work, but it is always pretty technical type stuff. No real room for imagination. Tips? Ideas? Commiseration? I feel like there should be "more" to me than this.
