There are usually guidelines for anything that does actually need to be kept, like financial records. If you're wondering about a given type of document, look for such guidelines from any organization that might require them at some point (e.g. the IRS for financial stuff). If it's a matter of sentiment, you're really the only person that can decide that, though you should make an effort to be cognizant about how much space you have available in which to do so and what effects such storage will have on the people around you.
