I Hate How Short-Tempered I Am. Rethinking It Through a Writing Habit
You want to stop being short-tempered and quick to snap. Before you decide temper is just your nature, try making your anger patterns visible through a record, and change without blaming yourself.
By Katsuki Mitsumori

A small remark sets you off and you snap back. Your kids or family do some minor thing and you raise your voice more than it deserves. Each time, a little later, self-disgust sets in: "I lost my temper again." You hate how short-tempered you are and want to fix it, but in the moment, the emotion always moves first.
It's easy to give up, telling yourself "temper is just my nature, it can't be changed." But how you react can change. This article shows how to make your anger patterns visible through a record, and adjust them little by little through a writing habit, without turning on yourself.
A Short Temper Is a "State," Not a "Personality"
If you believe "I just have a short-tempered personality," it can feel impossible to change. But much of a quick temper is governed less by inborn nature and more by your state of mind and body at the time.
Think back. Have you ever brushed off the same comment easily on a day you had room to spare, yet found it maddening on a day you were worn out? Lack of sleep, fatigue, hunger, the pressure of racing the clock: these quietly lower your boiling point.
And the stronger your rigid "shoulds" about how things ought to be, the bigger the anger when they're betrayed. In other words, a short temper isn't an unchangeable fate; it's the accumulated result of triggering states and beliefs. Once you see this, the heavy task of "fixing my personality" turns into the concrete work of "reducing my triggers."
First, Stop Blaming Yourself for the Temper
Desperate to fix it, many people scold themselves every time they get angry. But this backfires. The more you blame yourself, the more guilt piles onto the next outburst, and your mind wears thin. A worn-down mind gets even more short-tempered, a vicious cycle.
A short temper is both a flaw you'd like to fix and a sign that fatigue or stress has built up. Before blaming the version of you that snapped, ask instead: "Have I been overdoing it lately?" Sometimes it's simply that the foundation of resting, sleeping, and eating has crumbled, and once that's restored, the temper changes dramatically.
Make Your Anger Patterns Visible With an Anger Log
A concrete way to change a quick temper is the anger log: a habit of briefly noting, after the fact, whatever set you off.
You only need to write these four things:
- What set you off (the event)
- The situation you were in (place, time, how tired you were)
- How intense the anger was, on a scale of 0 to 10
- What thoughts ran through your head ("Why is it always me," and so on)
Keep it up, and you'll see that your anger has tendencies. You anger more easily when tired in the evening; you bristle when your plans are disrupted; your boiling point is lower with one particular person. Once you grasp these patterns, you can brace yourself in advance next time: "Ah, I'm in an easily angered state right now." Knowing the trigger makes coping far easier.
Writing painful experiences and feelings out has long been studied in psychology and is known to improve mood. The anger log is a record and, at the same time, an exit for releasing anger on the spot.
The Key to Keeping It Up: No One Else Can See It
What's essential for sustaining an anger log is the reassurance that no one else can see it. With an audience in mind, you unconsciously choose tidy words and paper over things with "I was partly at fault too." That way, the real triggers never surface.
That's why a fully private, locked space matters. Noroi Nikki was built to be that place. Write out anger as the "curse" it is, unseen by anyone, and you can later reread it to review your patterns. There's no need to reframe things positively or turn it into a letter of reflection. Start by writing out the day's anger just as it honestly is.
You can't change a short-tempered self in a day. But if you stop blaming yourself, learn your triggers, and restore the foundation of rest, how you react grows gradually calmer. And if you feel your temper is beyond your own control and is disrupting daily life, leaning on a professional or a support line is a perfectly good choice.

FAQ
Frequently asked questions
Q.Can a short temper actually be changed?
You don't have to force a change in your personality. Much of a short temper comes less from inborn nature and more from triggers like fatigue, lack of sleep, and rigid 'shoulds.' Once you know your triggers and make coping a habit, you can genuinely change how you react to the same events.
Q.How do I figure out my own anger patterns?
An 'anger log' helps: jot down what made you angry, the situation, how intense it was, and what thoughts ran through your head. Keep it up and you start to see which situations and beliefs set you off. Writing it honestly in a place no one can see lets you record and release the feeling at once.
Q.I keep blaming myself for being short-tempered.
The more you blame yourself, the more guilt piles on the next time you snap, which just drains you. A short temper isn't only a flaw to fix; it's also a sign that fatigue or stress has built up. Instead of blaming yourself, first learn your triggers and prioritize the basics of resting and sleeping.
Q.Is being quick to irritate related to being tired?
The link is said to be strong. Lack of sleep, fatigue, hunger, and time pressure all lower your boiling point. The very same event lands completely differently depending on whether your mind and body have room to spare. If your temper worries you, restoring rest first is the shortcut. If distress persists, consider talking to a professional.
