I actually disagree with Lya. The 10 things are all actions, not characteristics. It's akin to saying "10 things people who score higher than 30 on the MCAT do."
1) Set time aside every day to study.
2) Do practice exams.
3) Maintain their health
4) etc etc.
Therefore, I think the article is NOT implying that intuition is an intrinsic characteristic, but is instead a state of mindfulness that can be developed.
