Conditions that fortify creative work

[WonderSeeker]

Under what environmental conditions do you do your best creative work? Do you have any unique productivity habits? Special music that you play to get yourself in the right mood/head-space? What are your go-to methods for producing quality work in a timely fashion?

I'm writing a book and I'm trying out different music, nootropics, different rooms in the house, etc. Just wondering what other creatives find most helpful. Cheers!
