3. Write down decisions you make — and your rationale at the time — into a “decision journal.”
Next time you hire someone, cut a partnership deal, decide on a key product spec — or make any hard decision — write down your reasoning in a journal. Later, you can see how the decision played out relative to your reasoning at the time you made the decision. You can learn whether you should have trusted your gut at the time or not.
