You are eternal. You cannot change the fact that you have existed. The memory of God contains your story, and will never lose it. For all of eternity, no one can change the fact that you lived in certain places for certain periods of time. Such facts can be ignored, but not changed.
At the end of time God will tell the complete story of all people, of all time. Everyone will know what you did. (Will He let us also tell parts of the story? Will He tell us all what He intended/planned for/hoped for?)
Live a story you will be eager to tell.
