Salvete, amici! Vita me occupat, attamen Latine corde menteque semper vivo.
I found a quote of Seneca's I greatly admire (below), but I cannot for the life of me find the original Latin (at, say, TheLatinLibrary.com); first, I'm not sure if this is Seneca the Elder or Younger, and I haven't found the right word yet (apparently) to search for.
A single lifetime, even though entirely devoted to the sky, would not be enough for the study of so vast a subject. A time will come when our descendants will be amazed that we did not know things that are so plain to them.
— Seneca, Book 7, first century AD
