Hmmm - this is a good question.
Since I remodeled my room - I can say that I have so much more joy coming in here now that everything has a place and I can quickly - like 5 minutes or less - restore my room to neatness.
HOWEVER, once I start creating, everything can pile up around me until I have one square inch to work in and I could not care less. But at the end of that session I do need for everything to have a home to feel at peace
