When to Stash or Trash Important Papers
Some of us are pack rats by default; we don't know how long to keep what we think are important documents, so we store them in boxes indefinitely. Clueless clutter makes it difficult to find something when you actually need to reference it. Stop storing trash, and get organized when you learn how long you should hold onto certain papers.

Hang on to documents that have to do with your vehicle, like registrations, repair receipts, warranties, and user manuals, as long as you own the car.
Consider keeping receipts for expensive items in case you need to make an insurance claim, and it's always good to hold on to receipts for items that came with a warranty so you have proof of purchase.
