Get half of them superior education in politics and economics, if needed, help them acquire connections at high places and try to get them to as much of these high places as I can. Ideally presidents, big company CEOs and the like. With some luck I'll have the world in my fingertips.
The rest I'll educate into great physicists and engineers to speed up development of space travel and cryogenics all sorts of neat stuff, that would help me spread our lovely little species all over the galaxy.
