WRITING & REFLECTION

Keep a decision journal before you know the outcome

Record an ordinary choice, what you knew and what you expected, then revisit the result without rewriting your original reasons.

After a choice works out, its reasons can seem obvious. After it disappoints, the same reasons may look foolish. A decision entry saves the view you actually had before you knew what would happen, so a later review has something concrete to compare with the result.

Start with an ordinary choice: which afternoon activity to try, whether to bring a sketchbook on a walk or how to arrange a small making session. This guide is a writing exercise about your own reasoning, using a low-stakes example. You’ll record the options, the information available and an expectation, then keep the later outcome in a separately dated note.

A before-entry records reasons and expectations; a dated outcome is compared afterward.

  • A notebook or dated document
  • A pen or keyboard
  • One ordinary, low-stakes choice

Pick a choice small enough to describe

Choose a decision you haven’t made yet and can summarize in one question. “Will I spend Saturday afternoon at the open drawing session or take a walk?” is specific. “What should I do with my life?” contains too many decisions for this page. Give the choice a date or occasion so you know which instance you mean.

In a community thread about decision-making, writers discuss using structured columns when freeform thinking keeps circling. Farnam Street’s decision-journal method emphasizes recording reasoning before the result is known. This entry uses that timing distinction while keeping the example personal, ordinary and manageable.

WATCH & TRY

Keep the decision and result in order

The drawing-session example preserves what was known on each date.

Friday’s note records the reason and expectation.CHOICETry the open drawing session.EXPECTATIONFinish one sketch; meet othermakers.

Friday’s note records the reason and expectation.

It is written before attending.

Now try it on your paper.

Choose a low-stakes decision that has not happened yet.

Write the options and what matters this time

Name two or three real options, including postponing or choosing neither if those are available. Then list what matters for this particular occasion. You might want company, time outdoors, a chance to draw or a quiet afternoon. Avoid turning every preference into a permanent rule about yourself.

Write what you know beside what you’re assuming. “The session begins at two” may be confirmed information. “There will be people I know” may be an expectation. You don’t need a complicated scoring system. A few clear sentences can show which considerations are carrying the choice and which uncertainties remain.

“The original reason and the later result deserve separate dates.”

Describe an outcome you could recognize later

Before deciding, write what you expect the chosen option to be like and why. Include one uncertainty that could make the experience different. “I expect to complete one sketch because the session has a set subject; I don’t know how crowded the room will be.” That is easier to review than “It will be good.”

You can also name the tradeoff you’re accepting. Choosing company may mean giving up an afternoon outdoors. Recording that tradeoff prevents the later entry from treating every absent benefit as a surprise. The goal is a faithful snapshot of the choice, not a guarantee that you can predict the afternoon.

MAKE IT YOURS

Write the before-entry

Replace the example with an ordinary choice; keep uncertain information visibly uncertain.

AN EXAMPLE — MAKE IT YOURS

I’ll try the drawing session because I want company and a starting subject.

I expect one sketch; I don’t know how crowded the room will be.

I’m giving up the long walk. I’ll review after the session.

Your words have a place now.

Leave the actual outcome for a new, separately dated note.

Now try it on your paper.

Write this entry before making the choice, then add the outcome after it happens.

Read a complete before-and-after entry

Before, Friday: “I’ll try the open drawing session. I want company and a reason to use the sketchbook. I expect to finish one sketch because a subject is provided. I’m giving up the longer walk. I don’t know how busy the room will be.”

After, Saturday: “The room was busy and I made half a sketch. I liked hearing how two other people approached the subject. The supplied subject helped me start; finishing mattered less once I was there.” The review adds, “Next time I’ll describe what I want to try, not only what I expect to finish.” That last line arises from this experience, not from an all-purpose rule.

WATCH & TRY

Keep a retrospective account honest

The revision distinguishes a memory of a prediction from a saved prediction.

A reconstructed prediction is presented as if it were recorded beforehand.BACKFILLEDFriday: I knew the room would bebusy.WRITTENActually written on Saturday.SATURDAYRetrospective accountMEMORYI think I expected a busy room.

Starting version

A reconstructed prediction is presented as if it were recorded beforehand.

Now try it on your paper.

If you write after the event, label the account retrospective and preserve uncertainty in your recollection.

Separate the result from the earlier reasoning

If the afternoon goes badly, read the original note before calling the choice a mistake. Which parts depended on information you had? Which depended on an assumption? Which changed unexpectedly? A disappointing result and a reasonable choice can coexist, just as a pleasant result doesn’t prove that every assumption was sound.

If you forgot to write beforehand, don’t manufacture a dated prediction afterward. Label the page “Retrospective account” and note what you remember thinking. You can still reflect on the event, but it is a different kind of evidence from a note written before the outcome. Try the before-entry with another small choice.

Give the later review a narrow job

Choose a review point when the relevant outcome will be available: after the session, after using the new arrangement twice or when the borrowed book is finished. At that point, compare one expectation with what actually happened. Keep the original wording visible, and add the review beneath it with a new date.

Ask what you would want to know before a similar choice. The answer might be a practical question, such as whether the room has enough tables, or a preference you noticed, such as valuing conversation more than a finished drawing. It can also be “I’d choose the same option for the same reasons.”

WATCH & TRY

Ask one useful review question

Different results call for different comparisons.

Check an assumption that shaped the choice.ASSUMEDThere would be spare tables.LEARNEDI would ask about space first.

Check an assumption that shaped the choice.

Ask what information would help next time.

Now try it on your paper.

Compare one expectation with one outcome, then close with a single sentence worth carrying forward.

Finish without turning the journal into a judge

Close with one sentence about the reasoning you want to carry forward. Be specific enough that the sentence could inform another ordinary occasion, but leave room for different circumstances. “I enjoy a supplied starting point” is more useful here than “I should always join groups.”

The original reason and the later result deserve separate dates. Stop when you have a choice, an expectation, an outcome and one comparison. You don’t need to track every decision or rank yourself by how often events match your predictions. A few carefully chosen entries can make an interesting record of how you chose.
