Write down what you expect to happen when you make a key decision, then compare it with the actual results months later. Over time this reveals where your real strengths lie.
When to use it
Use it when you want an objective check on your judgement and strengths.
How to apply it
Record each significant decision or action and the result you expect.
Set a reminder to review it in nine to twelve months.
Compare the actual outcome with your expectation.
Look for patterns in where you performed well and where you did not.
Focus development on areas that strengthen what already works.
Tip: Keep entries brief so the habit is easy to sustain.
