Photography, to me, is all about bringing out some emotion in whoever is viewing your photographs. If you're taking a photo of something which doesn't bring any emotion out in you, chances are it won't bring out any in the viewer, either.
What do you love in life? Sports? Cars? Arcitecture? Music? People?
For me, one of my guilty pleasures is people watching. I love watching the body language, people's reactions and interactions. When I started getting into photography, I'd sit there watching people interact and photograph them. I do this mainly at parties, dinners and suchlike where I know people but occasionally do it when I'm sitting outside a coffee shop enjoying a cup of mud and a muffin.
I love these photos; something unique that can never be captured again. A permanent record of a moment gone in an instant. I look at the photos and, as there is emotion (implied or otherwise) in the photo, it brings out emotion in me and other people viewing the photo. If the photos were taken at a friend's party I'll pick my favorites, get some prints done and give them to the friend. Chances are, next time I go round there, the prints will be hanging on the wall. That's a fantastic feeling; seeing your work decorating your friend's home. Even if they don't like them, though, I love them and I'll hang them in my own home.
What I'm trying to say, in a long-winded roundabout way, is that you need to photograph something which you love. If you love or enjoy what you're capturing, you will see it in a way that nobody else can and your photographs will be glorious as you show people what you captured in a way only you can.
What do you love? What is it about that thing that makes you feel that way? Figure those things out and capture it. You might need to take some time away from the camera to figure it out but don't sell your gear whatever you do!
Hope this helps!
