We are all writing our own eulogies as we live. Our character is having a consistent impact on those that are close to us and forging strong bonds that will last long after we are gone. While I don't think we can live healthily by overanalyzing every word & action, we should still give some consideration to the legacy that we leave behind.
A life that is lived well by focusing on serving others will give us a foundation for positive impact. When we seek to honor God through the way we live it becomes less about our reputation and more about our allegiance to Him. That speaks a message that is so strong it will last long after we have breathed our last here.
