My former political science teacher

Around 2012, he dedicated himself fully to buying multiple properties in several provincial capital cities,
Around 2015, he deactivated his influential social media account and stopped making statements.
In 2018, he told us that a great change was imminent in history.
In 2019, he sold his houses at the peak price, leaving only two houses for himself.
In 2022, he used the money from selling his houses to start buying gold.
In 2022, in the second half of the year, he took a long vacation, neither getting infected nor vaccinated.
In 2023, after retirement, he went to the United States to retire with his daughter.
From my observation, he has a very obvious trait: extreme calmness, and he is good at analyzing problems from a structural perspective.
He doesn't like to analyze issues from human nature, emotions, or values, but prefers to analyze problems through logic, patterns, and structure.
Moreover, he never argues with others in public. Only during classes, when he encounters particularly trusted students, does he say some very insightful things.
At other times, he appears dull and ordinary, as if he has no special insights.
