Start the video gaem before going downstairs to brew a cup of tea, so that when get back to your desk you can look at the screen and go:
Oh hey, a video gaem!
And ask:
Who did that??
for real though this works really well for everything: do the easiest possible step of starting the thing, then go unload it from your brain, then come back if/when you're ready
gotta clean the tub? put the scrubby on the side and walk away for a bit
wanna make a music? open the DAW then go get a snack
need to cook? prep some ingredients then just put em back in the fridge
idk if it applies to everybody but for me so much of managing executive dysfunction is setting my life up to be full of "oh! an already-started and therefore easier-to-finish activity!" moments
