Our teacher when I'm in 3rd motivates us by arranging the our seats by rank and because I was hanging, I sat at the back and it' soooo shameful. So every grading she arranges us by our averages and it practically work for me because I was able to raise my rank. My motivation actually is food I won't eat that certain food I really want if I don't do good in this of that test. Or simply the doubts of people around me motivates me to prove them wrong.
