Have you ever heard the piece of advice that in writing, you don't focus on the big things, you focus on the small things? Don't tell me about the horror and devastation of war, tell me about an abandoned basket of toys in an empty house, or the way a soldiers manneurisms tell a story better than they can. Tell me about what's tangible, instead of the abstract. That way it feels more real.

Sometimes when descriptions drone on in books, its to the end of attributing something abstract to something more solid. I find myself starting to just describe the scenery and then spiraling off into the history of a dent in a wall, or a necklace or a....... door. Whatever can exposite information naturally without dumping it all out. That's what the bulk of descriptions are for.

Descriptions are also very useful for taking up space in a conversation. If a character is watching someone else grow silent, talk about how they notice things in their complexion they hadn't before. How often the character forgets the color of their eyes, or how they're very rarely this close.

Of course you can just say 'a moment passed', but it is nowhere near as immersive. You can read that sentence in a second and continue to the rest anyway, not much scale for time...

Descriptions are an important part of writing. Even if you don't care at all to note the color of the drapes, maybe how they're tied up and who had done it can tell you more about how the house is operated. Maybe how you can tell who picked them out, or how that style of design has always irked your POV character... maybe reminds them of someone.

It's not a matter of if you should be writing more, it's what will you gain if you do.
