How to Stop Making Bad Decisions That Cost You Money
I once saw a sign that made me laughโฆ until it didnโt. It read: โEverything happens for a reason. Sometimes the reason is you made a bad decision.โ Ouch! If youโve ever looked back at a money choice and wondered what you were thinking, youโre not alone. The good news? Bad decisions arenโt a character flaw. Theyโre a habit. And learning how to stop making bad decisions starts right there.
Hereโs the thing no one tells us: bad decisions rarely come from a lack of intelligence. They come from being human. From being tired, rushed, stressed, hungry, overly optimistic, or just plain worn down by too many choices in a single day. Even people who are capable, experienced, and generally careful can make decisions they later wish they could rewind. Not because theyโre reckless, but because life doesnโt always give us the luxury of perfect timing or a clear head.
Iโve learned this the hard way. Iโve made money decisions during seasons when I was exhausted or discouraged, telling myself Iโd โfigure it out later.โ Sometimes later came with interest, fees, or a knot in my stomach. Looking back, it wasnโt that I didnโt know better. I just didnโt slow down long enough to let what I knew catch up with what I was about to do.
Why Bad Decisions Keep Sneaking Up on Smart People
Whatโs interesting, and oddly reassuring, is that science backs this up. Research from the University of British Columbia found that a very small but powerful part of the brain plays an outsized role in how we make decisions. Translation: when weโre stressed, tired, or overloaded, that system doesnโt always fire on all cylinders. No wonder we sometimes repeat mistakes we swore weโd never make again. Itโs not weakness… itโs wiring.
The good news is that decision-making isnโt fixed. Itโs a skill that improves with practice. With a little awareness, some intentional pauses, and a bit of kindness toward yourself, you really can make better choices going forward. Not perfect ones… just smarter, calmer, more intentional ones. And those add up faster than you might think.
How to Stop Making Bad Decisions With a 24-Hour Rule
One of the simplest and most reliable ways Iโve found to avoid bad money decisions is a personal rule I follow without exception: I give myself at least 24 hours before I decide. I call it a time out. No buying, no clicking, no โjust one more look.โ I leave the store, close the laptop, and put the whole thing on the back burner for a full day and night.
It sounds almost too simple, but youโd be amazed how effective it is. That pause breaks the spell of urgency: the sale ends tonight, the deal wonโt come back, everyone else is doing it. More often than not, when those 24 hours are up, the thing that felt so important has lost its shine. Sometimes I canโt even remember why I wanted it in the first place.
And when the decision is truly important, the time out works just as well. Stepping away gives your brain a chance to catch up with your intentions. The noise quiets down. The pressure lifts. Whatโs left is clarity and thatโs where better decisions tend to live.
Learn From Past Mistakes Without Beating Yourself Up
When youโre facing a decision, it helps to look back… not to relive old regrets, but to gather useful information. Think about a time when you stood in a similar spot. What happened? What was going on around you? Were you rushed, tired, stressed, or trying to fix something fast? Those details matter more than the outcome itself.
If the last decision didnโt turn out well, resist the urge to label yourself. You werenโt โbad with money.โ You were responding to the circumstances you were in at the time. The value is in noticing the pattern, not punishing yourself for it. Once you can see what led up to the decision, youโre in a much better position to interrupt it.
History does have a way of repeating itself but only if we let it. You donโt have to make the same choice just because thatโs how it went before. The past is finished. The next decision is still yours, and itโs very much open for discussion.
How Fatigue, Stress, and Hunger Affect Your Choices
Iโve learned something about myself the hard way: when Iโm overly tired or hungry, I make terrible decisions. Not just small ones… expensive ones. I canโt think straight. I get impulsive. Things feel urgent that really arenโt. Knowing this, Iโve put a simple boundary in place that has saved me more than once: I donโt make decisions after the sun goes down.
By the end of the day, most of us are running on fumes. Weโve used up our patience, our focus, and a good chunk of our willpower. Thatโs not the time to decide what to buy, how to spend, or whether to commit to something new. So I wait. In the morning, after rest, a clear head, and something to eat, I check in with my stress level and start again, slowly and on purpose.
When you respect your energy, your decisions tend to follow suit.
When (and Who) to Ask for Advice Before Deciding
Unless a decision is deeply personal or truly private, donโt carry it alone. Call a friend. Take someone you trust out for coffee. Find a person who knows you well enough to listen carefully and honest enough to tell you the truth. Not to decide for you, but to help you see what you might be missing.
You donโt need a crowd or a committee. One steady, thoughtful voice is often enough to slow you down and widen the view. Youโre still in charge of the final call, but a second perspective can bring clarity, especially when emotions or pressure are running high.
And hereโs the quiet upside to getting it wrong sometimes: a bad decision doesnโt have to be wasted. If youโre willing to learn from it, it becomes experience… and experience is one of the most valuable tools you have. Each lesson makes the next decision a little steadier, a little smarter, and a lot less stressful.
Question: Whatโs one simple rule you follow now thatโs saved you from making the same mistake twice?

Mary Hunt2026-09-05 11:26:562026-09-05 11:36:10Should You Bail Your College Kid Out of Credit Card Debt?
I know this is a common one, but I finally learned not to shop for groceries when Iโm hungry. The amount of money and food Iโve wasted over the yearsโฆyikes!
With the current price of groceries, Iโm more determined than ever to avoid impulse buying.
I have a history of overspending via impulse shopping on Amazon. The things I’ve bought, I enjoy for a while, then they become clutter in my house. I have started using my Amazon wish list instead, and I take some time to consider whether I want these things. Lately I have deleted several things from my wish list.
Thats a great tip! You get the satisfaction of adding it to the list but give yourself some time to see if it was impulsive or something you really need or want. Thanks!
I definitely can relate to that sign you posted…been there…don’t want to go back there! I am forever recommending a book on Amazon “Easy Life Skills You Never Learned in School” — very simple, very easy, very low cost. We talk about de-cluttering all the time because you won’t buy things you already have; you make better decisions, etc. The same has to be done with the “junk mail in your head” — needless preconceptions of things you think you need or must do. Clear, creative thinking can literally change your life.
Hello, I wasn’t able to find that book you referenced on Amazon.
I loved luxury and unfortunately spent years mired in credit card debt because of it. I had no savings. What helped: figuring out what my hourly salary was and asking myself did I want to work XX amount of hours for it. Often, the answer was “no”.
I am the same, I really got into luxury pajamas and clothes once I was disabled, I just really wanted to be comfortable while I was in so much pain. Unfortunately I could not afford it so I had to stop so I could afford healthy groceries and utilities.
“Fatigue makes cowards of us all.” Vince Lombardi said. Most of my bad decisions come from not taking enough time to seek God’s direction and, more often, being so exhausted I can’t think straight. Like now. Winter in Appalachia has worn me down; thinking is hard, chores are hard…heck, breathing is hard! For the next few weeks, caution is my by-word; until it warms up, the snow melts and I’m able to do the work set before me…safely.
All good suggestions, Mary, but I have one more. Prayer. Ask the Lord to direct your paths – your decisions. Read the Bible – His Word for solutions both before a decision – for guidance, and if you have made a bad decision – seek His solution. If you are His, He has promised to guide.
Thank you for mentioning this, I need God to show me the path he’s chosen for me and I need to ask his guidance everyday to keep me on the right track..
