I figure that the end of the year is a good time to be focused on the positive. Chris Hadfield is a retired astronaut. A couple of days ago, he posted a YouTube video about his new year's resolution. He calls it "An Astronaut's Guide to Optimism", and it focuses on all of the human achievements of the last century. He also makes a suggestion about what your new year's resolution should look like. Have a watch. You may want to grab a tissue.
