Play politics well.
I’m not talking about state, national or foreign. Who the hell has any control over that crap? (You want to contribute to your favorite party or candidate, by all means do so. And certainly vote and be active. But don’t kid yourself you’re going to have huge or decisive impact, because you’re not.)
I’m talking about office politics. Here's a selection of the lessons I’ve absorbed about same as I’ve crawled along Life’s Highway ...
Minimize whining and back-stabbing. (You will probably do some of these things anyway, since most of us do. But keep it under control.)
Don’t make it personal (you’re working with these people, not marrying them.)
If you have a toxic personality, strive to hide it behind a fake, pleasant personality. Make work-time a popularity contest. You can go home and pull the wings off flies after hours.
Don’t rub your supervisor’s nose in his bad decisions. (“I told you so ...”) He'll make it his job to get you off his crew.
Stay in your damn chair, do your damn work, and don’t shoot off your damn mouth.
Understand that most of the office crises you encounter, the ones you thought were really huge deals at the moment they happened, will turn out to be pretty small bumps in your long-term career path.
