Mmmh, this is a difficult one. In science, like any other subject, you need to study material which does not seem too relevant to what you want to do. For example I remember when I was in college and was majoring in chemistry, I had to do an exam in computer programming!! I didn’t like it, I didn’t understand it, I didn’t see the point in doing it at all. I thought I was the most difficult exam of all which could have affected my grades. I passed it thought! And I suppose in a way it helped me not to be scared of learning new software for the many different instruments we are using in the lab.
oh, and getting your work published is not easy either!
