@davidrevoy I sometime use gnaural (available in AUR) tool “powernap” set to make a short nap, it is relaxing and regenerating. There is a 20 minute powernap set included, don’t know if it’s in gnaural itself or in gnaural-presets package. There is another one during 10 minutes with water like sound.

@davidrevoy sometimes you need to just take a break, disconnect, and reconnect with yourself. There is no shame in not producing things and you don't really owe anyone anything.
