The professor says that happiness is wanting what you have.Christian makes a thoughtful noise in the back of his throat. I see. Happiness is wanting what you have. Well, there you go. So what's the problem, then?What do you mean?Why is the class only okay?Oh. I bit my lip, then confess. Every time I meditate, I start glowing.
