The habit you do not need
Almost all habit advice adds something. The highest-return move most weeks is to remove one — and the candidates are easy to spot.
Habit advice has a bias: every piece of it recommends starting something. Nobody writes the article recommending you stop tracking your water intake, and yet for a great many people that is the change with the best return this month.
Routines accumulate the same way subscriptions do. Each was a reasonable idea once; none of them is reviewed.
Three that usually deserve removal
The one you are maintaining for the record rather than the result. If the streak is the reason you did it today, the streak is now the point, and the point was supposed to be something else.
The one measuring something you cannot act on. A number with no decision attached to it is a chore wearing a lab coat.
The one that was borrowed. Somebody else's morning routine fitted their morning. If you cannot say what it is doing for yours, it is doing nothing, politely.
How to remove one honestly
Stop for two weeks rather than deciding in the abstract. Two weeks is long enough to notice an absence and short enough to resume without having lost anything.
Write down what you expect to get worse. If nothing does, you have your answer; if something does, you learned what the habit was actually for, which you did not know before.
What this buys
Attention, which is the scarce thing. Every habit costs a small amount of daily decision-making even when it is automatic — the glance, the marking, the mild guilt. Three abandoned ones are a background noise you stop hearing and keep paying for.
