But just because certain personality characteristics correlate with doing well in grad school doesn't mean that students are powerless to increase their chances of success. Given the major role played by curiosity, for example, it's essential that students maintain their feeling of excitement about their field, the article advises, by guarding against trying to do too much. "Students who are pressured to finish their theses as quickly as possible, to publish too many papers or to attend one conference after the other will lose their curiosity for research," says psychologist Sophie von Stumm, a postdoc at the University of Edinburgh who studies academic success and is quoted in the article. "Students should make sure that they are looking forward to learning something new in each of those activities, rather than merely completing them because the supervisor or the school expects it."
This is only one of the suggestions for a successful graduate school career contained in the article, which you can find here.
