Why is the Rear-View Mirror smaller than the Windshield?

Cars are made with a very large windshield and a very small rear-view mirror because in order to drive safely and reach our destination we need to look forward more than we do backwards. Imagine driving down the road, focused most of the time with your eyes looking back at everything you pass while you’re speeding down the highway. We can imagine the eventual result of not keeping our eyes forward, or what happens when we aren’t focused on what’s ahead of us. How much time should we spend reflecting backward versus making sure we’re looking forward? The intent is for us to look forward rather than spending all of our time looking back. Hopefully, I’ll keep this in mind when I feel unbalanced. Sometimes my personal life intertwines or interferes with my business endeavors, and I need remind myself that in order to reach my goal I need to keep looking forward.
