Crossing into the blackness

I lost part of my Job Description today.
Since I got my car back, I have been lackadaisical and lazy about getting to work on time. My job wasn't worth the hassle, which is the wrong attitude to have at any time.
I have not lost pay, but I will no longer be using 3D modeling programs in an engineering sense. I will still get to use them for website perposes, but...
It seems to me that hitting bottom is something we do as a group. It's never a story of one person falling, It's a story of one person falling and the people around them being dragged down with them.
I'm still not sure where the line is, but I know it's coming fast.
