Sometimes it's better to turn off my computer or get away from my smartphone because I need quiet time to feel my body, hear my breathing, and listen to my inner mind. Doing nothing sets me to a default from which I can restart my work, whatever it is.
I also need quiet time with myself when I have important research tasks. Once I read enough resources, including books and articles in print or online, I sit with myself, take blank papers out, brainstorm, and begin to write article outlines. I completed three tasks this morning, making outlines for three chapters/articles. I can go back to my computer later to push myself further.
