I usually think of myself as being pretty "even" temperamentally. I don't often get stressed or uptight about things. I am not much of a worrier. But I know a lot of people who are. I've even tried to convince some of them that worry doesn't actually change anything (except within themselves - all change being for the worse). So I was a bit disconcerted when I received a link twice today for the same site - calm.com Are people trying to tell me something?
