"Imagine is More Important Than Knowledge"

Imagine about how my behavior would influence the other people.
Predict how they react when I take some action.

Then take some action if not inappropriate and observe.
Now I get one sample data.
Reconstruct my model (prediction) if needed then repeat the process at different incidence.

This is a science of human behavior.
First part is essential. I think everybody do "take action" and "observe" part.
But without "Imagine" part, it's not effective.
This will train my observational skill which is good to possess for better daily life.
