I'm roughly the same. Here's what I do.

I go to Staples and buy some bankers boxes. These are cardboard boxes that come in a flat pack and you fold the flaps in and make a box. It's sized to hold file folders, but I don't use file folders.

I write the year on the side and top of the box. Every imporant piece of paper, paid bill, receipt, credit card and bank statements, anything I want to hang on to goes into the box. That's it. No other organization. On January 1, I start a new box, and I put the old box on a shelf.

If I need something (which is much more rare than you might expect) I go through the box and find it. It's in roughly chronological order and generally doesn't take more than a few minutes.

After 5 years the oldest box goes in the shredder.

OK there are a few exceptions. Stuff I need to save longer than that (car titles, etc.) goes in a fireproof document safe. But all the common stuff goes in the box.
