Actually the same is true of "hard work". Conscientiousness is the personality trait of being careful, or diligent. Conscientiousness implies a desire to do a task well, and to take obligations to others seriously. Conscientious people tend to be efficient and organized as opposed to easy-going and disorderly. They exhibit a tendency to show self-discipline, act dutifully, and aim for achievement; they display planned rather than spontaneous behavior; and they are generally dependable. It is manifested in characteristic behaviors such as being neat, and systematic; also including such elements as carefulness, thoroughness, and deliberation (the tendency to think carefully before acting) [...] With the advent of the FFM (Five-Factor Model), behavior geneticists began systematic studies of the full range of personality traits, and it soon became clear that all five factors are substantially heritable. https://en.wikipedia.org/wiki/Conscientiousness https://en.wikipedia.org/wiki/Conscientiousness
