Is this true for your characters? What is under their noses, whether it be places to visit, friends to catch up with and so on, that they don't get around to actually do and which gives them cause for regret later on? Equally what long held ambitions do they finally get around to achieving and did the reality match expectations? (So often it doesn't!).
I've occasionally used settings I know well to flesh out descriptions in my fictional world. I guess you could say I was using what is right under my nose to good effect when I do that. So do you? What could you use to make your narrative deeper, easier to picture and so on?
