Organizing And Cleaning

I’m wondering what you guys do when there are things that need to be replaced, but you also kind of need them to serve a function until you replace them.

For example, there’s this old tiny mirror in my room that I want to get rid of, but then I would need to go out and buy a new mirror. What would you do in the time between when you’re ready to buy/replace all these things? Do you just get rid of it in hopes that it will motivate you to go get more? Another thing is a couch, but we aren’t in the place to spend the $$ to get a new one right now.
