How to Use a Decision Journal:
A Simple Template for Clearer, Calmer Choices

Knowing how to use a decision journal might be the most underrated confidence tool there is. It's simple: a notebook or document where you record important decisions, why you made them, what you expected, and how they turned out. Yet this small habit can quiet second-guessing, reduce regret, and help you become a wiser decision-maker over time.

Here's why it works. Our memories are surprisingly unreliable. Weeks or months after a decision, we tend to forget what we knew at the time, what we were worried about, and why we chose what we did. If things go well, we may think we were brilliant. If things go badly, we may think we were foolish, even if we made a perfectly reasonable choice with the information we had.

A decision journal keeps an honest record. When doubt shows up, you can reread your entry and remember your reasons. When an outcome disappoints you, you can see whether the decision itself was sound. And over time, you'll notice patterns: the kinds of decisions you handle well, the traps you tend to fall into, and the values that consistently shape your choices.

For women in midlife, facing big decisions about retirement, health, homes, money, and family, a decision journal can be a steadying companion. It turns decisions from swirling worries into clear, written choices.

In this article, we'll look at what a decision journal is, a simple template you can use, how to review it, and how it helps with second-guessing. There's a worked example, common mistakes, and answers to frequent questions.

We're in the Believe in Yourself stage of the BREW System here, under Second Guessing Everything. Keeping a record of your choices is a powerful way to build trust in yourself.

What a Decision Journal Is (And Isn't)

A decision journal is a written record of meaningful decisions. Each entry captures:

• What you decided
• Why you decided it
• What you knew and didn't know
• What you expected to happen
• How you felt at the time

Later, you add notes about how things actually turned out and what you learned.

A decision journal isn't a diary of every small choice. You don't need to record what you had for lunch. It's for decisions that matter to you, that you might second-guess, or that you want to learn from.

It's also not a place for self-criticism. The purpose is to understand and learn, not to judge.

Keeping it focused is a big part of knowing how to use a decision journal well.

Why a Decision Journal Helps with Second-Guessing

It preserves your reasons. When doubt shows up, you can reread your entry instead of reconstructing your thinking from scratch.

It separates decisions from outcomes. You can examine the information and reasoning separately from the result, while acknowledging that the causes may remain uncertain.

It reduces hindsight bias. Hindsight bias is the tendency to believe, after the fact, that the outcome was obvious. A journal shows what you actually knew at the time.

It closes the loop. Writing down a decision gives it a clear ending, which helps your mind let it go. Closing the Decision Loop explains more.

It builds evidence of good judgment. Over time, you'll see many decisions that worked out well. That's real proof that you can trust yourself.

Annie Duke's Thinking in Bets is a wonderful companion here. Duke, a former professional poker player, explains how to judge decisions by their quality rather than their outcomes, and recommends tools like decision journals to learn from experience without beating yourself up.

These benefits are exactly why learning how to use a decision journal is worth a few minutes per decision.

A Simple Decision Journal Template

You can use a paper notebook, a document on your computer, or a notes app. Here's a simple template with two parts: before and after.

Part 1: Before (at the time of the decision)

1. Date:
2. The decision: What am I deciding?
3. My options: What choices did I consider?
4. What I chose:
5. Why I chose it: My main reasons.
6. What I know: Key facts and information.
7. What I don't know: Uncertainties and risks.
8. What I expect: What I think will happen, and how confident I am, from 1 to 10.
9. How I feel: My emotions right now.
10. My values: Which of my values does this choice honor?
11. Tripwires: What would make me reconsider?
12. Review date: When will I look back at this?

Part 2: After (at the review date)

1. What actually happened:
2. How it compares to what I expected:
3. Was it a good decision, given what I knew then?
4. What went well:
5. What I'd do differently:
6. What I learned:
7. How I feel now:

You don't need to fill in every line every time. For smaller decisions, a few lines may be enough. For bigger ones, take your time.

This template is the simplest way to start learning how to use a decision journal.

How to Use a Decision Journal Step by Step

Step 1: Choose which decisions to record

Start with decisions that feel important, that you're likely to second-guess, or that you want to learn from. Examples include financial decisions, moves, health choices, career changes, travel plans, and family decisions.

Step 2: Write the entry at the time of the decision

Fill in Part 1 as close to the decision as possible, ideally the same day. This captures your real thinking before memory has a chance to change it.

Step 3: Set a review date

Choose a date to review the decision. For small decisions, a few weeks may be enough. For bigger ones, three, six, or twelve months may make more sense. Put the date on your calendar.

Step 4: Reread when doubt shows up

If you start second-guessing before the review date, reread your entry. Remind yourself of your reasons and tripwires. Treat tripwires as prompts rather than the only reasons to reconsider. New facts, safety concerns, deadlines, or changed circumstances may call for an earlier review.

Step 5: Complete the review

On the review date, fill in Part 2. Be honest and kind. Remember to judge the decision by the information you had, not just by the outcome.

Step 6: Look for patterns

Every few months, read through several entries. Look for patterns. Do you tend to be overconfident or underconfident? Do certain emotions lead to rushed decisions? Which values come up again and again? These patterns are gold for future choices.

How One Woman Used a Decision Journal (Example)

This is an invented example, a composite to show how a decision journal can work.

Irene is 59. She's been offered early retirement with a modest package. She's tempted, but scared. After weeks of thinking, she decides to accept. She knows she'll second-guess it, so she starts a decision journal.

Her entry:

• Decision: Accept early retirement.
• Options: Accept now, or work three more years.
• Why: I'm burned out. I have enough savings with careful budgeting. I want time with my grandchildren and to travel while I'm healthy.
• What I know: My budget works if I keep expenses steady and work part-time for two years.
• What I don't know: How the markets will do. Whether I'll miss work.
• What I expect: I'll feel relieved, with some adjustment. Confidence: 7 out of 10.
• How I feel: Excited, nervous, a little sad.
• Values: Health, family, freedom.
• Tripwires: If my savings drop more than a set amount, I'll look at more part-time work.
• Review date: Six months from now.

Two months later, the markets dipped and Irene panicked. She reread her entry. Her tripwire hadn't been triggered. Her reasons still held. She took a breath and let the decision stand.

At the six-month review, she wrote: "I'm happier and healthier. I miss my coworkers but not the stress. I'm glad I chose this. Lesson: I tend to underestimate how much I need rest."

Irene says the journal turned out to be most helpful during that market dip. Without it, she would have relied on her anxious memory of the decision, which in that moment said she'd been reckless. With it, she could see clearly that she'd made a careful, well-reasoned choice with a plan for exactly that situation.

Quick Versions of the Template

Not every decision needs the full template. Here are two shorter versions for everyday use.

The three-line entry

For small or medium decisions, try just three lines:

1. I decided: ______
2. Because: ______
3. I'll check back on: ______

That's it. It takes less than a minute, and it still gives you a record to reread when doubt shows up.

The one-page entry

For medium decisions, use one page with five headings: the decision, my reasons, my worries, my tripwire, and my review date. This version balances depth with ease.

Save the full two-part template for big, life-shaping decisions where the extra reflection is worth the time.

Shorter versions like these make learning how to use a decision journal easy to fit into a busy life.

Making Your Decision Journal a Habit

The best decision journal is the one you actually keep. A few tips:Keep it handy. Leave the notebook on your nightstand or pin the document to your computer's home screen.Pair it with a routine. Many women review their journal once a month with a cup of coffee on a Sunday morning.Make it pleasant. A nice pen, a favorite notebook, or a cozy spot makes the habit more inviting.Celebrate your reviews. Each completed review is proof that you're becoming a wiser, more confident decision-maker.

Once you've learned how to use a decision journal and made it part of your routine, you may find it becomes one of your most treasured records: a story of your own growth, written one choice at a time.

What Your Journal Can Teach You Over Time

After six months or a year, your decision journal becomes more than a record. It becomes a mirror. Here are some of the insights women often discover when they read back through their entries.

Compare your confidence with what happenedCompare your expectations with what happened across several entries. One good result does not establish that your confidence was too low. Next time you feel unsure, remember how often your "unsure" choices worked out.

Certain emotions lead to rushed choicesYou may notice that decisions made while exhausted, angry, or anxious tend to go less well. That's useful information. You can make a simple rule: no big decisions when I'm running on empty.

Your values are clearer than you realizedReading through entries, you'll probably see the same values show up again and again: family, freedom, health, creativity, security. Seeing them in writing makes it easier to use them as a compass for future decisions.

Bad outcomes aren't always bad decisionsSome entries will show disappointing results from thoughtful choices. That's one of the most freeing lessons of all. It means you can stop blaming yourself for things you couldn't have known or controlled.

You've handled more than you thinkPerhaps the biggest lesson is simply this: you've made many hard decisions, lived through the outcomes, and grown from them. That's real, written proof that you're capable.

Using a Decision Journal with a Partner

If you share big decisions with a partner, you can keep a shared decision journal for joint choices like moving, retiring, or major purchases. Each of you writes your own reasons, worries, and expectations, then you compare notes. This often brings hidden concerns into the open and helps you make choices you both feel good about. At the review date, sit down together with a cup of coffee and talk about what happened and what you learned. Many couples find these conversations bring them closer, because they're working as a team rather than second-guessing each other.

When to Reread Your Journal

Your decision journal is most helpful when you know when to open it. Here are the moments it's worth reaching for:When doubt shows up uninvited. Reread your reasons before you reopen the decision.When someone questions your choice. Your entry reminds you why you chose what you did, so you can respond calmly.Before a similar decision. Look at what you learned last time so you don't repeat old mistakes.On your review date. Fill in Part 2 and capture the lessons.When you need a confidence boost. Flip through past entries and notice how many decisions turned out well.

Think of it as a conversation with your past self. She did her best with what she knew, and she left you notes. Learning how to use a decision journal is really about learning to listen to her, and to trust her.

Common Mistakes with Decision Journals

• Writing entries after the outcome. This defeats the purpose. Write at the time of the decision.
• Recording too many decisions. Focus on the ones that matter.
• Skipping the review. The review is where the learning happens.
• Judging decisions only by outcomes. Good decisions can have disappointing results.
• Using it to criticize yourself. Keep the tone curious and kind.
• Making it too complicated. A few honest lines are better than a perfect template you never use.

Avoid these, and you'll quickly get the hang of how to use a decision journal.
