Research is pointing to conscientiousness as the one-trait-to-rule-them-all in terms of future success, both career-wise and personal.
“It would actually be nice if there were some negative things that went along with conscientiousness,” Roberts told me. “But at this point it’s emerging as one of the primary dimensions of successful functioning across the lifespan. It really goes cradle to grave in terms of how people do.”
What is it? Basically, it’s being “efficient, organized, neat, and systematic”:
Conscientiousness is the state of being thorough, careful, or vigilant; it implies a desire to do a task well. Conscientiousness is also one trait of the five-factor model of personality, and is manifested in characteristic behaviors such as being efficient, organized, neat, and systematic. It includes such elements as self-discipline, carefulness, thoroughness, self-organization, deliberation (the tendency to think carefully before acting), and need for achievement.
