KPIs is short for key performance indicators.
In order for you to know if you are making progress towards your vision and your goals, you need KPIs.
Some KPIs are straightforward such as weight or net worth.
In life areas where the vision is more subjective, it is harder to find KPIs. For these areas, it is more important to spend the time to find the KPIs so that you understand your progress.
Always be on the lookout for ways of measuring progress in all areas of your life.
