    This isn't quite what you're looking for, but you could label data. It's low effort (usually) and creates something useful, although it doesn't necessarily benefit you personally.

    Cooking. You start by following recipes, and slowly absorb the techniques and taste into your daily life.

    You can start cooking relatively cheaply. I do remember having sharp knifes and a good cutting board, some decent pans and you'll have a good time.

    Copy paragraphs from textbooks. Time-consuming but forces one to slow down and think.

    Memorization mnemonics. Shuffling through index cards to associate numbers to words. See Mind Performance Hacks (2006) from O'Reilly.

    Make notebooks with cheap filler paper, high-capacity stapler, and duct tape. Use G2 pens or archival quality ink.

    Make your own index cards: fold in half and then into thirds; cut those into rectangles. (Still on the lookout for good storage.)

    Shade paper with crayon. Carpet is smoother than desks. Envelopes are a good way to iterate color combinations. Pick colors at random.

    Convert mailed coupons into CSS. You get salable graphic designs and color palette for free.

    Break down milk cartons for free cardstock.

    Prime cardboard with paint for a cheap canvas.

    Pick up garbage at a local semi-wild area/walking path. Pay attention to nature and how the seasons change, as you pick up garbage. Enter trees and animals you spot into the iNaturalist app.

      I would generalize it to seeing trash in your daily walk. Not saying to to grab every piece of garbage, but even just one piece of trash tossed/recycled appropriately would make a difference.

    Without sweating the details, you could focus a bit on avoiding the annoying high-effort but useless activities that seem to come up too often under emergency conditions if you don't watch out :\

    Processing plant fibers for string/rope/etc. Nettle, yucca (so I've heard), hemp, ... it's a long list but regional.

    Humming to find the resonant frequencies of the space you're in.

    Observational drawing- paper, pencil, draw what you see (or if not sighted, maybe there's a similar activity?)

    Listening to what's happening around you. Originally thinking birdsong, but the lowest barrier is just where you are.

    I fly drones in simulators.

    The skills apply directly to real-world drones.

      Is flying drones a real world possible job?
      1. sejje 2 days ago
        Yes. The jobs I've heard about:

        * Military

        * Police

        * Search and rescue

        * Agriculture

        * Videographer (real estate being common)

        * Surveying

        I just fly for fun.

    Exercise.

      Walking or bicycling (or whatever mobility mode one can do), on the low-effort end, without sound in ears or eyes on screen; this lets the mind wander and eventually, interesting ideas and syntheses bubble up.

      Also just stretching, attempting balance, dance drills, etc.

      That's a good one. I was thinking more along the lines of something low effort that I could do at a desk or on a couch that will still lead me to improving a skill of some sort.

        Exercise while sitting down. Curls? Tricep pull-downs? If you do a bunch of squats, you could still be sitting half the time but getting fitness xp the other half.
