have you ever gotten into a routine that required a specific environment/ambience when working on a project? have you ever tried to only work under certain conditions? what were the results? is it best to always change up the environment? are there any more well-known books that resulted from such an experiment? i just feel interested in this because sometimes i get into a project and it requires the repetition of almost the exact same room, food, time, cat-petting, and music. but then, at a certain point, i change it all so i can test the moods in the project.
