Yes, I tend to do that a lot. Projecting happiness is quite easy, which is why people keep saying that smiling is the easiest thing to make you healthy. However, just because projecting happiness is easy, doesn't mean what I project is true. In fact, the sadder or the more worried I am on the inside, the more happiness that I project to prevent people from noticing that I was having a problem. Of course, I also have the intention that my happy face will somehow keep my mind healthy during time of sadness.
