How do you keep yourself just busy enough while listening to audiobooks?

I can't sit fully still and listen to an audiobook without a line of thought taking over. I often find that cooking, cleaning, and walking are decent enough activities to keep me focused on my book, but not distracting themselves. But sometimes I need to listen to 3 hours a day to meet my libraries check-out period and those activities aren't enough. How do you keep yourself busy through long books? Bonus points if I can meaningfully donate the output.
