We may not be able to control our external situation at all times, but we do have complete control over how we perceive the situations we encounter. This is the key to a better life.
Is it the number of years you live or the life in your years that's important. We all have to face death one day. Let's live our best life until we get to that moment.
I believe this is one of the most valuable concepts to understand if you want to get ahead and live a successful life. Play this for your kids over and over again.
