The Meaning of Life?

I'm starting this blog as a journal for my grandchildren. I've been trying to come to terms with the purpose of my life. What was the purpose of my time here on earth? What did I accomplish? What's my claim to fame? Up to this point I've been a daughter, sister, wife, mother and grandmother and I think I have progressively gotten better as I approach each one but I don't feel I've been successful at any of them YET. I feel like these things are what I WANT to be my claim to fame. Charlie teases me that I am the matriarch of the family, He doesn't realize how much of a compliment that is.
