Taking Stock: The Inventory of Life

What questions do you use for reflection and why?

Paraphrasing Tim Ferriss - Every 4-8 weeks at longest, I do 80/20 inventory of my emotional states. What are 20% of activities and relationships that are producing 80% of my positive emotional states and 20% of activities and people creating 80% of negative emotional states, the overwhelm, the guilt and so and put together a to-do list and a not-to-do-list accordingly. Specifically, the not to do list, the things to cut out.
