A Small Notebook for Decisions

The most useful entry in a decision journal may be a sentence beginning, “I don’t know.” It records the gap that existed before an outcome made everything appear obvious. Without that gap, a journal can become a scrapbook of explanations invented afterward.

A personal decision journal need not contain every choice. Recording which sandwich to order would make the practice tedious for me before it became illuminating. I would reserve it for decisions that involve a genuine tradeoff, a repeated difficulty, or an uncertainty I want to understand more clearly. Small and occasional is enough.

Imagine choosing whether to join a weekly evening class. The decision is ordinary, but it contains competing wishes: learning something new, keeping evenings open, meeting people, avoiding another obligation. A journal entry can hold those wishes together without forcing them into a grand account of personal identity.

Start with the decision in one sentence. “I will try the class for four weeks.” A bounded choice is easier to examine than “I will become more creative.” The first describes something that can happen. The second invites an argument with yourself about what sort of person you are.

Then write the main reason. Not every reason, and not a defence prepared for an imaginary critic. Perhaps the reason is that a regular time would help you begin something you keep postponing. Perhaps curiosity is enough. A plain statement gives your future self something specific to revisit.

Add the alternative you considered seriously. This matters because decisions happen between available options, not between an action and a perfect world. In the class example, the alternative might be setting aside one evening at home. Comparing the class with doing absolutely nothing would quietly exaggerate its appeal.

Now record the uncertainty. “I don’t know whether the travel time will make this feel like a chore.” That sentence may be more useful than a confident prediction about enjoying the subject. It identifies the part of the decision that experience can actually clarify. It also suggests what to notice during the trial.

You can include a modest expectation, provided you label it as an expectation. “I expect to look forward to most sessions” leaves room for an inconvenient evening. “This will transform my routine” creates an unnecessarily dramatic test. Ordinary decisions deserve ordinary measures of whether they are working.

Choose a review point that fits the decision. For this hypothetical class, the end of the four-week trial makes sense. The date is a reminder to look back, not a deadline by which life must deliver a verdict. Sometimes the honest review is that you need more experience or that the original question has changed.

At review time, separate the result from the reasoning. A disappointing class does not prove that trying it was foolish. An enjoyable class does not prove that every assumption was sound. Ask what you knew, what you reasonably could have known, and what surprised you. This keeps the exercise from becoming a ceremony of praise or blame.

It helps to preserve the original entry. Resist editing an old uncertainty into something more sophisticated. Add a dated note underneath instead. The awkwardness of the earlier version is part of its value. It shows the actual shape of your thinking before experience tidied the story.

If the journal begins to feel like supervision, make it smaller. Four lines can be sufficient: choice, reason, uncertainty, review. There is no prize for creating a comprehensive archive of yourself. The point is to leave a few honest markers in a landscape that memory keeps repainting. Over time, those markers can help you notice which concerns deserve attention, which predictions you repeatedly overstate, and which decisions were reasonable even when their outcomes were imperfect.

You might eventually notice a recurring pattern: perhaps you underestimate the effort of travelling, or prefer a short experiment to an indefinite commitment. Keep those observations tentative. A handful of entries can suggest a better question without establishing a permanent rule about your preferences. The notebook should help you stay curious about your choices.
