Great tips so far!
What I want to suggest is to think outside the box. Bend the rules a little
If you only take photos by the rules or ideas other people have about photography(or what they like), your photos will not be so special. Try different things.
Try shooting a landscape with the longer end of your lens or try shooting a portrait with the wide end of your lens. Change perspective, lie on the ground for once or climb a tree. Those things will make your shots more special. You can also try making panorama's or HDR's. Shooting an extra photo does not cost any more, so use that as an advantage.
I must admit that I personally also tend to grab the wide angle on my lens to capture a sunset or sunrise, but the fact is that the photo can be just as nice or maybe even better when you use a longer focal length. For example, the sun looks a lot bigger when you use the long end of your lens.
Just an idea. Good luck!
