Some times it's better to not include the sky
Especially when you live in areas that don't provide the grand wide open landscape opportunities, it's time to "think small".
As my friend Rick Sammon would say, "find the picture inside the picture". Get in close, narrow your field of view and find more creative intimate shots. One trick to learning how to "see" this types of shots is to purposefully avoid the sky in landscape shots. It will force your mind to think more creatively and start to see the lines and elements available to you.
Stay in focus,
