There's a lot of fanciful stuff about "creative" and "absent-minded" people doing the best work, but what actually makes a good researcher is the same as in any other field: (a) curiosity (b) determination, and (c) hard work.
PhD programs don't take people who just have a good GPA; you have to have a research record before you're even in the consideration. I've been on an admissions committee, so this is not conjecture.
