The positivity movement in America is to always put a positive face on it, and never ever to mention anything dark. Have you read Barbara Ehrenreich's book Brightsided?

I am a realist. Doesn't mean that I don't put my best foot forwards at all times. Doesn't mean that I don't get up when I'm down. However, I don't believe in positive thinking, and a while ago, a study came out that negative people achieved just as much as positive people - for different reasons. They were so scared that something bad would happen that they did something about it! :)
