One key is to appreciate that you are gainfully employed and have a job to do. It can be all too easy to get bogged down in the day-to-day frustrations, but taking a step back and acknowledging the value in what you do can be a powerful motivator. Another important step is to use your proper chain of command and be part of the solution, not part of the problem.
By doing these things and staying focused on your responsibilities, you'll be well on your way to conquering those feelings of frustration and having a more positive work day.
