The first course that I did in Scientology was the simple Communication Course and fortunately for me I wasn't going very well on it. The supervisor started to check my understanding on it, asking for a demonstration etc. which I wasn't able to carry out too well. I could feel the emotion of anger starting to rise in me because I felt so stupid, and fortunately for me before I exploded, I got the simple (but huge for me) realization that I KNEW I DIDN'T KNOW. And from that point on I was willing to learn, and that hunger has never stopped.
