A related area is focusing on key objectives and tasks each day. Some of our https://weekdone.com/ weekly planning & status reporting service users have allow people to list 3-5 key goals per week and do things only if they match those 3-5 goals. Having tried that myself with our team as well, it's hard as hell. You always end up doing something from your 20-50 small todo list items, not the 5 big things.
