Explain the Difference Between a Habit and a Routine

You keep trying to build a habit and it keeps slipping, and you wonder why. This prompt explains the real difference between a habit (automatic) and a routine (deliberate effort), with a concrete example of each and why the distinction changes how you go about building one. Good for anyone trying to make a new behaviour stick and getting nowhere.
