To decide whether a habit is helping, compare what you hoped it would change with what you have actually experienced. Include the effort it takes and anything useful it displaces. Completing a routine tells you that you did it; it does not settle whether the routine is worth keeping.
This review is for optional everyday habits, such as planning your work, reading or taking an evening walk. Do not use it to change prescribed treatment or dismiss professional advice.
Write the original reason in one sentence
Try “I started doing this because I wanted…” If you cannot remember the reason, describe what you currently hope to get from it. A clear intention gives the review a direction.
“Read ten pages every night” describes an action. “Enjoy a quieter end to the day” describes one possible purpose. If the reading has become a rushed obligation, the action and the purpose may need to be reconsidered separately.
Look at four kinds of evidence
- Outcome
What, if anything, has changed in the situation you care about? Use concrete observations rather than an overall verdict about yourself.
- Experience
How does the habit feel before, during and afterward? Enjoyment, irritation and relief are useful context, even when they vary.
- Cost
What time, money, preparation or mental effort does it require? What else no longer fits?
- Circumstances
What else changed during the same period? A lighter workload, illness, travel or support from another person could affect the result.
A journal is an incomplete account, not a controlled experiment. You may write more on difficult days and forget to record uneventful ones. A pattern can suggest a question to explore without proving a cause.
Choose a review period that fits the question
Set a date rather than checking constantly. For a small planning routine, you might review after several ordinary workdays. A habit whose purpose takes longer to observe will need a different timescale. There is no universal number of days that proves a habit is effective.
That question is also different from how long an action takes to become more automatic. Our habit-formation research guide explains why a fixed deadline can be misleading.
Keep, adjust, pause or stop
- Keep when the benefit still matters and the effort fits.
- Adjust when the intention is useful but the timing, size or method creates problems.
- Pause when your circumstances make a fair review difficult or you need space.
- Stop an optional habit when its purpose no longer matters or its costs outweigh its value to you.
You can also write “I do not know yet” and identify what information is missing. Continuing temporarily is different from assuming you owe a routine permanent loyalty.
A worked example
Fictional example: I began reviewing tomorrow’s tasks at night to make mornings simpler. It helped me remember appointments, but I kept opening work messages afterward. I will keep the three-item note and write it before leaving my desk. In a week I will check whether mornings are still easier and evenings feel more separate.
The adjustment changes one part of the routine and names two things to notice. It does not require a perfect streak. If the result is unclear, the writer can reconsider rather than adding more tracking fields.

Save the review alongside the original intention. When you return to it, you can compare your reasons as well as your actions. That is often a more useful question than whether you maintained the longest possible streak.
