I feel that traits such as diligence and confidence will help anyone to become academically successful. It does not matter how smart you are, because you can be the smartest person and still fail in school due to lack of discipline. Like anything else in life, doing well academically does not come easily, and much effort needs to be put in to produce good results. Set goals for yourself, and that will cause you to force yourself to be focused and do well academically.
