What is the priority for your MC right now? — 46

We'll start at the very beginning of the story. The MC is 142 and on his deathbed. He has, maybe, a few hours to live. Memories of his former lives are suddenly starting to come to him.

He thinks back on the many lives he's lived, but ponders more deeply about the life he's just about to leave. He thinks of his children, grandchildren, great-grandchildren, and even a few great-great-grandchildren.

He's left many lives unfinished, and doesn't want this to be one of them.

His priority now is to ensure his children are left with the knowledge of how much he loves them, and how enriched his life has been because of them.

He wonders if his next life will be as fulfilling as this one.
