The best investors keep decision journals. Here's why it's one of the highest-leverage habits in high-stakes decisions, and how AI maintains it for you.
The best investors keep decision journals. So do the best founders. It's one of the highest-leverage habits in high-stakes decision-making - and almost nobody does it consistently. Here's why it matters, and how AI is finally making it automatic. A decision journal is a record of your significant decisions - what you decided, why you decided it, what information you had at the time, and what you expected to happen. You revisit entries later to see how things played out and what you can learn.
