Heres a cool survey to take on Job Satisfaction.

I got 30-somethin % dissatisfaction and this message:
Your job is not bad, but it's probably not a long term thing.
You're just not happy enough to stick around for too long...
And there's little that can change how you feel.
Start looking around for other options, but only quit for something really good!
Try it.
