For the first time in as long as I can remember, I'm really happy. Not the kind of happy that comes from the outside - when your job, relationships, and the weather are good. Happy in spite of external stuff. It's quite wonderful, and I hope it lasts.
The one thing I've learned, though, is that happiness is tiring. I feel the need to go places and do things and see people, which doesn't quite mesh with the reality of having to go to work the next day. I've been out late 4 nights in the past week, and it's taking a bit of a toll on me energy-wise. But I've had a boatload of fun, and I can always sleep later.
