The first thing I tell teams of people who are struggling is ML: Make a list. Write down the list of problems to solve or issues to fix. Get it out of their brain and on paper. It's less stressful when its written down. Then put them in order of importance, with an order that everyone understands: what comes first, what comes next, and so on. Making good ordered lists is the fundamental thing any effective leader does, and it's the heart of popular planning methods like Kanban and SCRUM.
