"To ensure a safe learning environment, you have to make sure to accept all answers, and build on them. We should view students as plants and flowers that need careful cultivation: grow some areas, help reduce others. [...] There is really no upper limit on learning since the neurons seem to be capable of growing new connections whenever they are used repeatedly. I think all of us need to develop the capacity to motivate ourselves. One way to do that is to search for meaningful contact points and bridges between what we want to learn and what we already know. When we do so, we cultivate our neuronal networks."
