Routine is great for keeping yourself accountable and on track. But, after a while, you build that consistency up over time. Like you said, you no longer need the routine to maintain your productivity. You've already unlocked that ability with weeks, months, and years of consistency. The other benefit of a routine is not so much adherence to a strict schedule. But, making sure you complete certain tasks each day. It's not the when that is important. Just that you devote some time to the task itself.
