In business and politics — unlike in football and chess — knowing previous “games” well doesn’t necessarily provides a big advantage.

The validity of the environment is extremely low. Even though some of the situations and cases might seem like something that happened before (”history repeats itself”), in reality there is a multitude of factors that are totally different.

That’s why all these “business success” stories are mostly worthless.

That’s why seeing great leaders in action right now is so much better than reading their decade-old books.
