Mostly, 2014 was a wild rollercoaster of downs and ups. Overall, I'm not sure hitting 40 had any major significance other than making me feel old on forms.
Things definitely feel different than they did at the beginning of last year. For now I'm going to go with "better than before". That's not to say my life doesn't feel a wee bit askew a lot of the time, because it does, but for the moment, I'm working on it.
