Habit is the nursery of errors.

Mistakes do not usually begin as decisions. They begin as something you did the same way often enough to stop looking at, and then the flaw inside it gets repeated at full speed, protected by the fact that nobody looks at it any more. Routine is useful precisely because it runs without attention, and that is also the danger. The error grows up quietly inside it.

Take one thing you do on automatic, at work or at home, and do it slowly once this week while watching your own hands. Ask why each step is there. Some of them will turn out to be there for no reason at all.
