I liked Manya Whitaker’s piece on How to Find a Writing Routine That Works. I think the relationship of stress to the situation: Your emotional state has a direct effect on brain functioning and the corresponding relationship to marking the end of your intellectual work for the day.
I watched this one, which was languishing on my my “Read It Later” list. I can only assume it appeared when I needed to hear it most, could integrate it into my being the most. It may not be flashy, but damn, it is solid! https://www.youtube.com/watch?v=WWloIAQpMcQ&feature=emb_logo
I am going to try this trick as it is less expensive than purchasing something. Hope it work.
