A friend of mine said something powerful at his grandfather's funeral. He said that the greatest lesson from his grandfather's life was that he died empty, because he accomplished everything he wanted, with no regrets. I think that, along with leaving a legacy, would be the greatest sign of success.

This quote speaks about the importance of living a full life and leaving behind a legacy. It means that when someone dies, they should have accomplished everything they wanted in their life, so that they have no regrets. This is the greatest sign of success, because it indicates that the person lived life to its fullest and left behind a legacy for others to remember them by.
