Do no evil
No job is worth an ulcer! Therfore, the best remedy for a bad day at work is to see the good in those that share the immediate suffering, because most jobs are not so bad it is just that some people in the mix of management tend to not care for those that get the job done. This is not a good thing. Many people in positions of power need to re-look at how what they do and say affect others, because good really does more that you think!
