Nothing.. Just want get off this rock and seed the galaxy.. With variations of humanity (i.e. modifying the human race to survive on different planets)..
These seeded planets, would you leave them to evolve on their own or would you give them instruction booklets on how best to conduct themselves?
I'd recommend James Blish's "The Seedling Stars" and Frederick Pohl's "Farthest Star".
It's a fascinating subject for creative speculation.
