What is accomplished in the late years?

Since I am approaching my eightieth birthday next month and if I am lucky enough to make it, I have been wondering what can I accomplish. I don't have much to my credit in the previous years so what would be possible for me to achieve in the late years. Looking back in history we see examples of individuals who continued to use and enhance their creative gifts into very old age. Verdi composed his "Ave Maria" at eighty-five. Pablo Casals played the cello, conducted orchestras, and taught up to the time of his death at ninety-six. Ralph Vaughn Williams composed his eight and and ninty symphonies in his eighties. Grandma Moses took up painting at the age of seventy-seven and continued to do her quaint and appealing work to the end of her life at ninety-nine. Michaelango worked on his sculptures virtually until his death at eighty-nine.
Arthue Fielder vigorously conducted the Boston Pops orchestra in his eighties, and Arthur Rubenstein at eighty-eight continued to recieve standing ovations for his piano concerts.
I could go on and on with others but we must accept the fact that these were exceptional gifted people. But they do give proof that creativity and fresh ideas the power to enrich one's society and culture need not vanish with old age.
Creativity in one's later years does not fall like manna from heaven. It requires an abiding interest in life and conviction that we can continue to grow, learn, and create to the very end of our days.
I have to ask God daily to let me stay until I have accomplished what is still pending in my own life. Resigning of a leadership role continues to haunt me daily but my fellow Shepards insist that I still play a vital role. However, I have to ask God what the future holds and just ask for him to give me the wisdom to decern what is best and hopefully I can still be effective. We all want to grow old but growing old has its problems that has to be dealt with. All we have and are is due to HIM.
