I am in total control of my mental faculties and the environment I create.

Environment is a grand word for something quite small: what sits within arm's reach.

A phone on the nightstand and a phone across the room produce two different people in the morning. So does fruit on the counter versus fruit in the drawer. So does whether the running shoes are visible from the front door.

Nobody has total control of their mind at three in the morning. Everybody has control of the nightstand. Arrange the near things while you are calm, and they will do a surprising amount of the arguing for you later.
