How Do I Stop Second-Guessing Myself at Work?

Steve Peterson walked the plant every morning for three hours. Every line, every cell, every break room. He would stop at a machine, ask a good question, nod at the answer, and move on to the next one. By half past ten he had seen everything in the building and decided nothing.

I used to shake my head at those walks. Then it hit me that I did the same thing sitting down. I was second-guessing myself at work all day long. I once reread a two-line email to maintenance until second shift clocked in. Two lines. I could have carved it in stone faster.

So here is the short answer. You stop second-guessing yourself at work by deciding with what you know right now, writing down why in one sentence, and setting a time to look at it again later. Then you leave it alone until that time comes. Second-guessing feels like being careful. It is not. It is the same decision, made over and over, with no new information coming in. That is not caution. That is a loop.

Why do I second-guess every decision at work?

Most people who second-guess themselves are not dumb and they are not lazy. They are usually the conscientious ones. They care about getting it right, and at some point getting it wrong cost them something. A boss who made an example of them. A mistake that got talked about in the break room for a month. After that, the brain puts a guard at the door, and the guard checks every decision twice. Then it checks the checking.

Underneath most of it is one quiet belief: my judgment is not good enough to trust. That belief is where the self-doubt lives. You would never say it out loud. But watch what you do. You ask three people before you make a call you are fully qualified to make. You rewrite the email. You walk back to the machine to make sure you really did lock it out, even though you remember doing it.

That is a confidence problem wearing a safety vest. You cannot fix a problem you keep calling a virtue.

The switch that would not stop chattering

Here is the best picture of second-guessing I know, and it came off a plant floor, not out of a book.

A mechanical switch does not close cleanly. When the contacts come together, they bounce. For a few thousandths of a second the switch goes on, off, on, off, on, before it settles. A person pushing the button never notices. But a controller reading that switch sees every bounce, and if nobody tells it otherwise, it thinks the button got pushed six times. Now your counter is wrong and somebody is standing at the machine scratching their head.

The fix is called a debounce. You tell the controller: when this switch changes, wait a set amount of time, then read it once and believe it. That is all. The switch did not get better. The rule for reading it did.

Second-guessing is contact bounce in a person. On, off, on, off. Yes, no, maybe, yes. And the fix is the same one we put in the controller. Give yourself a set window, read the situation once, and then believe the reading. You do not need a better brain. You need a better rule for when to stop listening to it.

How much information is enough to decide?

A lot of overthinking decisions comes from waiting for a certainty that is never going to show up. You want to be sure. At work you almost never get sure. You get likely.

Here is a rule of thumb I have used for years. When the next piece of information would not change your answer, you have enough. Ask yourself, "If I found out one more thing, what would it have to be to make me decide differently?" If you cannot name it, or if you could name it but there is no way to get it this week, you are done gathering. You are just stalling with a clipboard.

Steve's walkabout was information gathering that never ended. Every stop was a good question. None of them led anywhere, because there was no point at which he said, "That is enough, here is what we are doing." Good decision making at work is not knowing everything. It is knowing when to stop looking.

Write down why, then walk away

This one sounds too simple to work, and it is the one that works best.

When you make a decision, write one sentence in a notebook. "Ran the second shift on line three short one person because the rush order matters more than the preventive maintenance this week." Put the date on it. That is your reading. That is the debounce.

Now when the doubt comes back at nine o'clock that night, and it will, you have something to answer it with. You do not have to re-argue the whole case in your head. You look at the sentence and ask one question: has anything actually changed since I wrote this? If nothing has changed, the decision stands. The voice in your head does not count as new information. It is just the switch bouncing.

And the notebook does something else over time. It becomes a record. Six months from now you can flip back and count how many of those calls turned out fine. For most people it is a lot more than they would have guessed. That record is how you start to trust your own judgment again. Not by talking yourself into it. By looking at the evidence.

How do I stop overthinking small decisions?

On the floor we had a simple way to sort jobs. Is it a bolt or a weld?

A bolt you can back out. If you put the bracket in the wrong spot, you loosen it, move it, tighten it again. Ten minutes and a little pride. A weld is different. Once it is done, undoing it means a grinder, a mess, and maybe a new part.

Most decisions at work are bolts. Which job to run first. How to word the email. Whether to call the supplier today or tomorrow. If you are wrong, you back it out and try again. Those decisions deserve a minute or two, not an evening. Save your careful, slow thinking for the welds: firing someone, signing a big contract, taking the new job. Those deserve the time.

The trouble with chronic second-guessing is that it treats every bolt like a weld. So you spend weld-level worry on bolt-level choices, and by the time a real weld comes along you are too tired to think straight.

How do I learn to trust my own judgment?

Here is a question I ask people who tell me they cannot trust themselves. If a technician on your crew had your exact track record, the same years, the same calls, the same misses, would you trust them? Almost everybody says yes. Some of them get a little quiet after they say it.

That gap is what John Maxwell calls the Law of the Mirror: you must see value in yourself to add value to yourself. People who second-guess everything are usually giving everybody else in the building more credit than they give themselves. They will take a new hire's read on a machine before they will take their own.

Self-confidence at work does not arrive as a feeling first. It gets built from small kept promises to yourself. You said you would decide by noon and you did. You wrote down why and you did not reopen it. You got one wrong, backed out the bolt, and the building did not fall down. Each of those is a deposit. Nobody else sees them. You do, and that is the point.

When I was twenty-three I had a mortgage, a baby and a full-time job, and I second-guessed nearly everything, because nearly everything felt like a weld. What finally helped was not a pep talk. It was noticing, slowly, that most of my calls were fine. I just had never kept score.

Be honest about what this costs

I will not pretend this is free. If you decide faster, you will be wrong more often in public. Some of your bolts will need backing out while people watch. That stings, especially if you have spent years avoiding it by checking everything three times.

But count the other side of the ledger. Second-guessing costs you too, it just costs you quietly. It costs you the evenings you spend replaying the day. It costs your crew, who stand around waiting for a decision you already made twice. It costs your reputation in a way you do not see, because people stop bringing you problems that need a fast answer.

And one more honest thing. Sometimes the doubt is right. If a decision keeps bothering you and you can name a real, specific reason, that is not bounce. That is a signal. Go check it. The skill is not ignoring every doubt. It is telling the difference between a doubt with a reason and a doubt with a habit. And if the self-doubt is constant, follows you home every night and starts eating your sleep, that is worth talking over with a doctor or a counselor. There is no medal for grinding through it alone.

Common Questions About Second-Guessing Yourself at Work

Is second-guessing yourself a sign of low self-esteem?

Often it is tied to how much you trust yourself, but not always. Plenty of confident people second-guess one area, usually the area where they once got burned. Look at where it shows up. If it is everywhere, work on trusting your judgment in general. If it is one kind of decision, go back and find the moment that taught you to doubt it.

How do I stop second-guessing myself after I make a mistake?

Own the mistake, fix what you can, and write down the one thing you would do differently. Then close the book on it. The lesson is worth keeping. Replaying the whole scene every night is not a lesson. It is a rerun, and reruns do not teach you anything new.

Should I ask my boss before every decision?

No. Ask your boss once where your authority ends. "Which calls do you want me to bring to you, and which ones do you want me to just make?" Then make the ones that are yours. Most bosses would much rather hear "here is what I decided and why" than "what do you think I should do?"

Is second-guessing ever a good thing?

Once, yes. A second look before a weld is smart. A fifth look at a bolt is not. The first review catches real mistakes. Every review after that, with no new information, is just the switch bouncing.

Reflection Questions

1. What decision are you circling right now, and what is the one fact that would actually change your answer?
2. Of the calls you second-guessed last month, how many turned out wrong? Be honest, and count.
3. Where did you learn to doubt your own judgment? Can you name the moment?
4. Which decisions on your plate are bolts, and which are welds?
5. If a coworker had your track record, how much would you trust them?

The Bottom Line

Second-guessing is not care. It is contact bounce, the same yes and no flickering over and over while nothing changes. Put a debounce on it. This week, buy a cheap notebook. Every time you make a real decision at work, write one sentence about why and put the date on it. When the doubt comes back, ask only whether something has actually changed. If it has not, the decision stands.

So let me ask you. What is the one decision you already made, maybe days ago, that you are still remaking every night?

This ties back to The Law of the Mirror — one of John C. Maxwell's 15 Laws of Growth.
