If you aren't back to where you began, all it means is that the journey is not yet over. Maybe, it will take a life-time; may be many. But you will end your journey exactly where you began. This is the nature of life. Even the Universe will end it's journey exactly where it began - in the infinitesimal black hole of absolute death. And on the other side of that death, life will begin once again in a massive big bang. And so it will continue in a never ending cycle.
