I think most engineers know that doing everything right is reserved for toy problems. In engineering you're always making choices about what problems to deal with today and which to leave for tomorrow. Code is always some kind of simplification of reality: reality is just too damn complicated. The rules of the game of tech debt are the same as the rules of thermodynamics and the game of being alive: you can't win, you can't break even, and you can't even stop playing the game.
