Most of the time I liked school and got good grades. In junior high, though, I hit a stumbling block with math - I used to come home and cry because of how frustrated I was! But after a few good teachers and a lot of perseverance, I ended up loving math and even choosing it as a major when I got to college.
Students never think it can be the teacher's fault and so I thought I was stupid. I was frustrated and would come home and cry because I couldn't do it. Then we got a new teacher who made math accessible. That made all the difference and I learned that it's how you present it that makes it scary or friendly.
