Getting more difficult

It's getting harder for me at work to concentrate on doing my job. I pray that this is only a phase I'm going through. Please! I'm pretty sure that I've already mentioned that I've never been at a job for 3 years and i'm hovering at 2 1/2. but that's so not an excuse for me to be feeling like this. I also feel like a total buzz-kill. So, I just have to suck it up, put on a happy face, and remember how it was like when I first started. I was a go-getter. Always asking for what projects to work on. Coming in early and was the last one out. I need to get back into that mode! basically putting as much energy into work as I do with my pursuit of being a playwright.
