Well, maybe, do we have some genes responsible for the degree of a person's industriousness? It's just that some people seem to lack it, while others have it hypertrophied😁 And if we go deeper into this question, we do find such a pattern in heredity. The "industriousness" gene (under a slightly different name) is one of the "big five" according to the generally accepted classification of human temperament. Five complex characteristics have been identified, and they all have high heritability: extraversion, neuroticism, benevolence, openness to experience, and conscientiousness. Hard work is 40-60% determined by genes🧬 And the remaining percentage is determined by the characteristics of the environment, culture, upbringing. That’s a very high degree of inheritance, and it can have a significant impact on a personality.
