If you like digital systems (like me) and you'd like to reduce the amount of paper clutter in your life, then consider using a note-taking app to go 100% paperless.
I use Apple Notes (but you can use whatever you prefer) to store all sorts of digital paper: e.g. Instruction manuals, journals, receipts, business cards and even sentimental things like birthday cards. In my view, keeping these things in a digital system makes them easier to find later and having less physical clutter in your life is also a bonus.
