A friend of mine from high school is now the CEO (or some clever, start-uppy title like Comrade Evangelist) of a small high-tech start-up in Cambridge. I recently read an interview with him in a start-uppy online magazine in which he described the daily routine in his office this way: “It’s basically heads-down until lunch–and then we come out and start having meetings.”

“Heads-down”: This term fills me with existential dread.
