I am Cristina K. When I was a student, my favorite teacher told me one day: “everything is difficult before it is easy.” I didn’t get it right away, but in time it became more and more clear for me that difficult materials are easy to learn or memorize when I understand them or when I make a correlation between them. I try to be logical, and any material that I find difficult to understand, I organize in my notebook. And I discovered something else very important for me at that time: in order.
