This video suggests identifying what you're optimizing your life for and then reverse engineering out anything that doesn't contribute to that objective. Activities can be categorized into four buckets: happiness, success, happiness deserts, and success deserts. Non-essential activities that don't contribute to the ultimate objective or that you don't enjoy or aren't good at should be eliminated or outsourced, delegated, reduced, automated, or regulated. The focus should be on activities that you love and are good at, as this increases effectiveness and efficiency.
