I Tracked Every Decision I Regretted for 30 Days

I didn’t set out to do this as some kind of self-improvement project. It started almost as a joke — I said something snippy to a coworker, immediately regretted it, and thought, that’s the third time this week I’ve felt this exact feeling. So I opened a notes app and started logging it. One line a day, minimum: what I did, why I regretted it, and how big the regret actually felt on a scale of 1 to 10.

Thirty days later, I had a strange little dataset about my own brain. Here’s the full log, unedited, followed by what it actually taught me.

The Daily Log

Day 1 — Regret Level: 4/10 Said “no worries” to someone who was, in fact, worrying me a great deal. Spent the rest of the day mentally rehearsing the honest version of that sentence I didn’t say.

Day 2 — Regret Level: 2/10 Bought a coffee I didn’t want because the barista remembered my usual order and I didn’t have the heart to correct her. Drank half of it out of guilt.

Day 3 — Regret Level: 7/10 Skipped a workout to “rest,” then spent the entire evening feeling worse than if I’d just done twenty minutes. The rest was not restful. It was just avoidance wearing a nicer outfit.

Day 4 — Regret Level: 3/10 Sent a text with a typo to someone I was trying to impress, then sent a follow-up correcting it, which somehow drew more attention to it than the typo itself ever would have.

Day 5 — Regret Level: 6/10 Agreed to a weekend plan I didn’t actually want, purely because saying no in the moment felt harder than the entire weekend would.

Day 6 — Regret Level: 1/10 Ate the last slice of cake without asking if anyone else wanted it. Nobody said anything. I still felt it.

Day 7 — Regret Level: 8/10 Let a disagreement with a friend go unresolved instead of just calling to talk it through, telling myself it would “blow over.” It did not blow over. It just went quiet, which is worse.

Day 8 — Regret Level: 2/10 Stayed up late doom-scrolling instead of reading the book on my nightstand that I keep telling people I’m “in the middle of.”

Day 9 — Regret Level: 5/10 Didn’t speak up in a meeting when I had a genuinely useful idea, then watched someone else say almost the same thing ten minutes later and get credit for it.

Day 10 — Regret Level: 3/10 Overexplained a simple decision to someone who didn’t ask for an explanation, turning a two-second interaction into an unnecessary five-minute justification tour.

Day 11 — Regret Level: 9/10 Made a joke at a family dinner that landed wrong and changed the mood in the room for the rest of the night. Nobody said it was a problem. Everybody knew it was a problem.

Day 12 — Regret Level: 4/10 Bought something online at 1 a.m. that I returned four days later, having fully forgotten why I wanted it in the first place.

Day 13 — Regret Level: 2/10 Cancelled plans with a genuine excuse, but felt guilty anyway, as if the excuse being real somehow made it worse instead of better.

Day 14 — Regret Level: 6/10 Half-listened to someone telling me something important while glancing at my phone, and they noticed, and I noticed them noticing, and neither of us said anything about it.

Day 15 — Regret Level: 1/10 Took the highway instead of the shortcut out of habit, cost me six extra minutes, and thought about it far more than six minutes deserves.

Day 16 — Regret Level: 7/10 Didn’t ask for help on a project until it was nearly too late, because asking earlier felt like admitting something I wasn’t ready to admit.

Day 17 — Regret Level: 3/10 Laughed at a joke that wasn’t actually funny because everyone else was laughing, and spent an embarrassing amount of energy wondering if anyone noticed the laugh was fake.

Day 18 — Regret Level: 5/10 Compared myself to someone online for a solid twenty minutes before catching myself and closing the app, already knowing the mood damage was done.

Day 19 — Regret Level: 2/10 Left the gym after ten minutes because it “felt off,” which in hindsight was just the first ten minutes of every workout, which always feels off.

Day 20 — Regret Level: 8/10 Avoided a difficult phone call all day, which didn’t make the call easier — it just meant I carried the dread around with me for twelve extra hours for nothing.

Day 21 — Regret Level: 4/10 Said “I’m fine” to someone who clearly wanted the real answer, and watched the conversation end somewhere shallower than it could have gone.

Day 22 — Regret Level: 3/10 Didn’t take a photo of something genuinely beautiful because I told myself “I’ll remember this,” which, statistically, I will not.

Day 23 — Regret Level: 6/10 Chose the easy task on my list over the important one, and ended the day busy but not actually any closer to anything that mattered.

Day 24 — Regret Level: 2/10 Reheated leftovers instead of cooking something fresh, then felt a wildly disproportionate amount of disappointment in myself over a bowl of rice.

Day 25 — Regret Level: 5/10 Interrupted someone mid-story because I thought I knew where it was going. I did not know where it was going. It was a better story than the one I assumed.

Day 26 — Regret Level: 3/10 Said yes to something out of guilt rather than desire, and spent the rest of the day quietly resenting an invitation I technically accepted willingly.

Day 27 — Regret Level: 7/10 Didn’t tell someone something kind I was thinking about them, because the moment felt “too much,” and then the moment passed, the way those moments always do.

Day 28 — Regret Level: 1/10 Forgot to water a plant. The plant was fine. I was disproportionately relieved.

Day 29 — Regret Level: 4/10 Checked my phone during a conversation that deserved better than that, and the person I was talking to didn’t call it out, which somehow made it worse.

Day 30 — Regret Level: 6/10 Ended the month by rereading this entire log in one sitting, and regretted, briefly, how much of it I already recognized before I’d even written it down.

What 30 Days of Regret Actually Revealed

Reading back through the log, a few patterns showed up that I wasn’t expecting.

The highest-regret days were almost never about mistakes — they were about avoidance. Days 7, 11, 16, and 20 all scored highest, and none of them involved me doing something wrong in the traditional sense. They involved me not doing something: not calling, not asking for help, not addressing the joke that landed badly. The lowest-scoring regrets — the coffee, the cake, the highway — were all actions I actually took. The things I avoided hurt more than the things I got wrong.

Small social regrets outnumbered big practical ones by a wide margin. Out of thirty entries, roughly two-thirds were about some version of the same thing: saying the wrong amount, listening the wrong amount, or being present the wrong amount with another person. Almost none were about money, work performance, or anything that would show up on a resume. The regrets clustered almost entirely around connection — moments where I either gave too little of myself or performed a version of myself I didn’t fully mean.

The regret score dropped fast once I named it. This was the most surprising part. On days where I caught the regret in real time and either fixed it or at least acknowledged it out loud, the number I gave it at the end of the day was consistently lower than on days where I just silently carried it. Day 26 — saying yes out of guilt — only became a 3 instead of something higher because I admitted to myself in the moment that I was doing it. Naming the thing seemed to shrink it slightly, just by making it visible instead of ambient.

Almost nothing on this list will matter in a year. I want to be honest about that, because it would be easy to read thirty days of regret and conclude something dramatic about needing to overhaul my entire personality. That’s not really the takeaway. The coffee, the highway, the plant — none of that needs fixing. What’s worth paying attention to is the smaller cluster of avoidance-based regrets, the ones about calls not made and things not said, because those are the only entries on this list that are still, weeks later, quietly unresolved.

If I kept doing this for another thirty days, I don’t think I’d expect the number of regrets to go down. I think I’d just want the kind of regret to shift — fewer entries about things I didn’t say, and if I’m being honest, I’d take thirty more days of forgetting to water the plant over even one more day like day 11 or day 20.
