tombstonic 

Life's work. Lifetime achievement. Worthy of mention on a tombstone. A source of pride and contentment in one's final hour. Rhymes with "boom's tonic".

"It's a good job, but I can't make a difference in the world that anyone will care about. Nothing I'll do there will ever be tombstonic."
