Then what we should do?

Become more logical and less emotional. You need to remember some of these points:

• Data is King: Knowledge about something, anything comes from data.

If you never wanna hurt by someone you admire, try to collect data. Observe them and wait for real data.

• First impressions are horsesh!t: first impressions dont come from data, but from how you perceive the world- which relies solely on your level of intelligence and knowledge.
