I prefer to have clean space to feel more comfortable and have less things on my mind. I will have my humidifier with a calming scent on or a nice candle. I will sometimes even take breaks, drink water and stretch. maybe even go outside with my airpods and read depending on the days weather. It just depends on what makes you as comfortable and calm as you can. I try even putting myself in the main characters position or read a book that relates to me more or something i’m interested in at the moment. It makes a book more meaningful to me and makes me more interested in it.
