I tend to see communicating with others as a phenomenon that brings you out of a shell you've created for yourself. It's important to have both attributes, a balance of extroversion and introversion. When I tutor math I feel this shell coming back. The fear of math problems came back slowly, but now that I'm going more often I fear this is going to be an endless cycle. Is it too selfish of me to ask for more chemistry students when there are clearly so many people that need help with math? And is it okay to not remember how to do a problem?
