I learned that the easiest and fastest way to make a decision is to count from 5 to 1. This is a practice that one of life coaches and successful people use to arrive to a conclusion. If you are thorned in many options just go 5-4-3–2-1 and make that move. Easy right? Try it. It will help you fail fast to succeed faster. 

For instance, in lining up in a restaurant and your main goal is to pursue your diet and go for healthy-meal choices just go 5 to 1 and you will pick the healthiest in the menu. I think it is the magic of instinct and fast decision-making. 

However, in dealing with hard-life choices, I think you can use this rule at about 50-80% of success. If you are dealing with your relationships or your job and business, I think it requires a little bit of faith and grace of god, combined with the rule can greatly change your life.
