Well, if you want to live to see it done within your lifetime, that would justify the hurry.
I don't think I'll ever live to see humans get much farther than Mars at best before my clock winds down.
Even if by some miracle we find a workable hyperdrive technology some time before I croak... I'm positive I'll never see manned missions take place to the outer reaches. The first several hundred hyperspace flights to other solar systems will no doubt be unmanned probes.
