In my younger years, it was problem-solving. How can I do this presentation without so much speaking? What other methods are there? It made me talk to my teachers about the problems I was having. I was asserting myself against the idea that I just needed to relax (a lot of teachers had no idea what I was dealing with). In adulthood, it has been the ultimate friendship-filter. Some people pounce on your weakness and make you feel it even more. Seeing that knee-jerk reaction tells you a lot about how they view others. Other people ignored it. Others ask great questions. It helps me select the people that will be important in my life. If someone couldn't comprehend what I was dealing with then they probably haven't had much adversity in their life. Those people are boring.
