When you are seriously overwhelmed with work, your first instinct is to work faster. Rip through your projects at break-neck speed so that you can get more done in the limited time you have. Of course the faster you go, the sloppier you are and the more errors you make, so there's definitely a trade-off. This morning I ran across a mistake from yesterday's work that was so massive that I very nearly had to fire myself. Fortunately, I caught the problem before it blew up and destroyed half the galaxy. Because, you know, my job is heinously important like that. And, if you didn't know, I guess you do now.
I am dreading going to work tomorrow for fear of what mistakes I might find from today.
I was working on four projects simultaneously, so who knows what could have happened?
If the earth explodes because of another careless error tomorrow, I'm really sorry about that.
