Descriptive narrative is hard. Its important, but its not. It slows down a story for most people. Ill bet you most of us, reading a novel loaded with description, will unconsciously skip it and get to action or dialog.
The trick is to make description very potent, or mix it in with action and dialog. And even more important, consider your audience. If youre writing a thriller, description should be crisp and brief. If youre writing chicklit, the audience is going to want to be there, to see it.
I personally can write pages of dialog with little effort. Description slows me way down, and is drudgery.
Do the work of good description for scenes ... your reader will appreciate the help in 'being there' more readily. The most endearing aspect of Mickey Spillane novels is the descriptive work which places the reader squarely in the scene. Reading adventure novels (for instance) sweeps the reader into 'another world' ... escaping for a time the world around them.
I'm like you. I can write page after page of dialoge, but when it comes to descriptive.... I just feel like I'm slogging away. And it reads like that too.
Attempting to write action, on the other hand, I find excruciating. I can't picture action scenes. I'm the same way with movies - in a long action sequence, I have to struggle to keep my focus. My mind just switches off.
Fortunately, there's no one correct way to write. ;-)
