There is a persistent feeling of never having enough time. I am constantly watching my wristwatch. Is this how time ends, with an exhausted, stressed longing for more? It would be nice to quote Heracleitus here but I don't know where my English-translation copy of Fragmente der Vorsokratiker is.
Ah, I found it! It's where I thought it was.
Heracleitus, Fragment 123: "Nature likes to hide."
