Your post really resonates with my own experience. When things are in order in my environment, creativity and the feeling of well-being flow with ease within me.
I believe is because, as you also mention, being in an orderly space frees some important mind space from mundane worries (the dirty dishes in the sink, the clothes piling up in the corner) and lets your brain focus on what is truly important.
Also, for many of us who are prone to anxiety, the feeling of lack of control can be crippling. However, organizing and clearing your personal spaces helps gaining some sense of control back. A great antidote!
Last but not least, your painting is extraordinary. A true artist really makes the most out of any circumstance, right?
Thank you @irime! I cannot say for sure which follows which. Re-ordering our mental and emotional space vs our personal exterior spaces. It seems to be, if you start with one the other will follow.
I believe this is why monks and nuns of what ever religious persuasion keep their spaces assiduously clean and tidy, it helps with the inner peace and builds a discipline of the heart and mind.
That is not meaning to say, eliminate all chaos from our lives. We do need a little of that, as it is what makes us alive... especially if one is an artist. ;-)
