user-1: I am looking for sutta text where the Buddha says something like...

The ways of the world will never be finished find your own salvation
  with diligence...

Meaning, all the politics, hatered, war in this world will always continue you need not heed them and instead you should work towards your own salvation...

user8157: Possibly Pupphavagga or Lokavagga or Jesusvagga.

178. Better than sole sovereignty over the earth, better than going to heaven, better even than lordship over all the worlds is the
  supramundane Fruition of Stream Entrance.


user254: There are some (famous) lines in the Maha-parinibbana Sutta (DN 16)

Therefore, Ananda, be islands unto yourselves, refuges unto yourselves, seeking no external refuge; with the Dhamma as your island, the Dhamma as your refuge, seeking no other refuge.

And

Behold now, bhikkhus, I exhort you: All compounded things are subject to vanish. Strive with earnestness!

These don't quite match, "The ways of the world will never be finished"; but they are a good (maybe the best) match for, "find your own salvation with diligence".
There are various English translations, e.g. it's often translated "diligence" instead of "earnestness".
