Why do I worry so damn much?

Seriously, I don't know why, but I do. I mean today I learn that someone at my station was "let go" (fired) because of a bad 20 month review. Granted, I don't know what specifically this guy did, or what transpired to get this guy in this position, but it worries me. I mean, I didn't exactly get off to a roaring start, and I'm not exactly the best at any one thing at this job. I do show up on time, everyday, haven't called in sick, look clean, and make a sincere attempt to learn and perform this job. But I still have to wonder, what will happen at my 20 month review?

Something else that bothers me is that some of the guys gossip like teenage girls. "This guy's a shitbag, that guy is lazy, that guy is...." It's like the only person at the whole damn place that knows it all is the guy talking to you. I just keep my mouth shut and try to avoid doing stupid stuff. This only ties in because when people talk, your reputation can precede you. I don't need any more bad press.

I know that the only thing to do is to double my resolve, do the job better and better everyday, and just take it one day at a time. And relax. It's not so much about cramming everything in at once now, but rather getting a nice, easy ascent into this job. I can do that. I just have to focus and stop worrying.
