What is preventing you from living peacefully?

Say what you want, but I still know that I don't need algebra. And it's not because I don't understand it. I don't understand chemistry either, to put it mildly... but I maintain a grade of 4 or 5 because I NEED it. Moreover, veterinary medicine is just a plan... I don't even know yet where I'm going to study. So... I really don't understand complex calculations. I have a different way of thinking. A creative one.
