Great analogy on deadlines for engineers.

Similar to a soccer game when your opponent leads 0:1 and there are only 5 minutes left on the clock. The team will try everything to score asap. But outside of such pressured situations the team simply focuses on ball possession and making good plays. There is nobody asking the players at what time they will score the first goal. Not before the game and especially not during it.
