Teel,
For me, there is something great out there. The universe. At least, it's great enough for me. And, oh yeah--even just our little world, the planet Earth. It's certainly great compared to tiny me. And one more thing--the human race. Pretty amazing and great. Lots of faults, and sometimes individuals are bad--but they are quite interesting and amazing at all the things they can do as individuals, as groups, and in their entirety. If that's not enough to keep a someone going, just finding one person that you truly love might do it. Especially if they love you back.
All I can really tell you is that I am never at a loss of "things out there to keep me going." If anything, there's an oversurplus.
