FAQ
What should be mandatory in every decision journal entry?
Thesis, downside case, invalidation trigger, and review date should always be present.
Can a simple template outperform complex notes?
Yes. Short, repeatable structure usually improves consistency more than long unstructured commentary.
How soon can journaling improve outcomes?
Most investors see process improvements within one to two review cycles when entries stay consistent.
