Less is more. When I was teaching writing and publishing at a local community college, I asked my students to write about walking into a hospital. They gave me long, florid descriptions of sights and smells and sounds. Then I shared mine:

"I walked into the hospital."

That's oversimplifying my point, but the point still needs to be made. Everyone has been in a hospital. Everyone can picture it. Don't waste words writing stuff the reader already knows. Thinking visually doesn't mean bogging down the story with minutiae.
