Of the big 5 personality traits in psychology, the three most highly correlated with success are: high disagreeableness, high conscientiousness, low neuroticism.
So there's an interesting give and take here.
So there's an interesting give and take here.
High disagreeableness means being able to dismiss most people, because most people will tend to pull you in towards a regression to the mean.
Low neuroticism is about stress tolerance. Doing anything major/new/difficult is stressful.
High conscientiousness means you spend time preparing, finish important tasks right away, pay attention to detail, and work well on a schedule.
It's hard to imagine being highly successful at much if you can't handle stress, are disorganized, and are very sensitive to others trying to tell you to do what everyone else does.
High conscientiousness gives you the power to achieve it.
Low neuroticism helps you avoid self-sabotage.
