A day is a week

The phrase "It's a marathon, not a sprint" feels nice and comforting until you remember that the best marathon runners in the world are running sub-5-minute miles for 26.2 miles.

An hour at a startup is like a day at a "real world" job.
A day is like a week.
A week is like a month.
A month is like a year.
A year is practically an eternity.

Startups without existential urgency don't win.
