Anything that can't go on forever will eventually stop.

Everything has to come to an end, sometime.

Since it could be done what was the use of doing it, and anyway you always have to stop doing something sometime.

Human misery must somewhere have a stop: there is no wind that always blows a storm; great good fortune comes to failure in the end.

Even nothing cannot last forever.

Nothing lasts forever, few things even last for long: all are susceptible of decay in one way or another; moreover all that begins also ends.

Nothing is forever...nothing lasts

It will all stop someday, but not for billions of years. Many billions. Even the stars run down, you know. Entropy must increase.

Everything comes to an end. A good bottle of wine, a summer’s day, a long-running sitcom, one’s life, and eventually our species. The question for many of us is not that everything will come to an end but when. And can we do anything vaguely useful until it does?

Everything has to end before it can begin.

If you just keep doing, you will burn out and grind to a halt.

There has to be an end somewhere, he thought. Each thing has to end, or there will never be any room for beginnings.

Pleasure comes, but not to stay;
Even this shall pass away.

Nothing lasts for ever.
