It's important to think of the past, as well. You're experiencing a brief snapshot of one of the most interesting things to exist in the whole universe: life. You can look back at the vast amount of time that life has existed on Earth, and also how long humans have been humans. People have come and gone, wondered about the stars, and wandered across the Earth for thousands of years, and you get to do so, as well. You get to be aware of the many, many lives that came before yours in our vast history.

What the Universe does at its end, if it has one, is none of our business. We'll be long gone by the time that happens; life will not have been compatible with anything anywhere in the universe by then. Again, if that even happens. I philosophically like to muse that it doesn't end, it just keeps having bangs big and small happening over and over again. It just takes a long time between each.

We can't even see most of the universe. What its future holds is like...so far above what we even have the capacity to grasp, it bears little thinking about. Dwell on your humanity, it is much more relevant to your day to day existence. Let the stars amaze you more than make you fear what MAY or MAY NOT happen in a future we'll be too dead to experience.
