Nihilitarianism

I keep thinking that something better will come along every time I've gotten everything done and there's nothing left to do. But what if there won't, and at some point I just run out of things to do and there's just emptiness for the rest of my life? I might as well think, what if I run out of breath for the rest of my life? To stop learning is to die. And the longer I spend in emptiness, the greater the next idea that will come out of it. But it's hard to balance it. Sometimes I pursue the emptiness only to end up despairing when it's there. And sometimes I can't catch up with it, because there are too many ideas to go through. It's a careful balance, but one thing I know is that I must make peace with the possibility of the emptiness appearing at any unexpected time in the future.
