From Peter Bregman in 3 Timeless Rules for Making Tough Decisions.
Use habits
For decisions you know you need to make on a daily basis, you want to reduce decision fatigue. Don’t spend time on deciding where to get lunch.
Use if/else logic
For decisions with unclear choices that you make on a daily basis. Using predetermined logic helps.
Use a timer
Often times there is no clear answer at the time. Save time by reducing deliberation. Excessive data collection, opinion gathering, evaluating pros and cons all hope to give a clearer answer, which may not happen.
