The whole "if you don't have anything nice to say, don't say anything at all" philosophy is clearly so not me. If things are down, there's always something to moan about. If things are up, I'm too busy enjoying them to say anything!
So for the record: I'm not a miserable downer. I'm not always going through a hard time or bemoaning the fate of my world. Things aren't always hard.
In fact, things are great. All the things that really matter put a smile on my face, a spring in my step, a song in my heart, and all manner of other cliches. Now we all just have to remember what really matters.
