In grade eight I took physics. In one test I get only 36 percent of the answer correct. I failed the next one, either. I started to think that maybe I was not good at it. However, I was not lucky enough to have a teacher which didn’t take my bad grades as a judgment of my abilities, but simply like an indication how I should study harder. He pulled me aside and told me that he knew I could do better. He permitted to retake the test, and I was pulled my grade to an A. This is what I discovered: just because a subject is difficulty to learn, it doesn’t mean you are not good at it.
