You can get into a flow state when cooking or cleaning. The task just needs to be in a specific Goldilocks zone of demanding and feasibility.
Cooking eggs, to me, might get me in a flow state, but probably not a trained French chef, unless they were pushing themselves to elevate the dish.
Probably not when watching movies though, unless you were constantly analyzing the story… maybe in a mystery flick or something.
If it's something special, that demands skill and investment and yields better than average results, it's worth figuring out how to trigger it consistently. But then it's harder to argue I can achieve something like it by doing something so easy and trivial as cleaning the house.
So is it trivial and just a well known mechanism by another name and thus just a label that muddles the waters, or is it something special, thus quite apart from just focusing on something, that merits effort, and should not be conflated with trivially achievable states of mind?
Edit: I might be overstating the ease of getting into flow for neurotypical folks, having just googled it I’ve found a few references to studies showing those with ASD get into a similar state of flow very easily.
The researcher responsible for the term and idea wrote a book saying as much. https://www.amazon.com/Flow-Psychology-Experience-Perennial-...
It’s great that making eggs is easy enough for you that it isn’t engaging, but that isn’t the case for everyone (I need to try to fry eggs over easy. I’m not a good cook) You can also trick your mind into entering this state with a wide variety of tasks.
