Affiliate Marketing Secrets

My boss/dance director wants to meet with me tomorrow, and I am incredibly nervous. I am guessing she wants to talk about the dance classes that I may possibly teach this summer. She is not the easiest to talk to, and like last time, I am afraid of the pressure she is going to put on me to teach too many classes, and I do not have that much of a free summer. So, first question: how should I handle it if she puts to much pressure on me? I do not want to quit, I have been affiliated with this business a long time and they are family to me. Second question, how can I relax and stop being so anxious?
Thanks!
