"It's more than a little comforting to know that people can become happier, that pessimists can become optimists, and that stressed and negative brains can be trained to see more possibility." - Shawn Achor This is a quote from the post from Huffington Post. I'll wait here while you go read the article. It mentions a bunch of the things that we have already talked about on this blog, exercising, being kind do others, meditating (or praying), but it adds in a few I haven't heard of, such as abandoning shallow small talk and talking about things that matter. It's worth taking a look if you haven't already.
