Mike, In a perfect world we should be cold-blooded when undertaking our actions. But it would be just the perfect world. In our reality our emotions usually drives us to do something, instead of sitting and waiting for a change which never comes. Serious decisions should be made when you’re calm but personally I use my emotions as a catalyst to act. After day or two you can forget how much you hate the place (or whatever your reasons are). On the other hand, when you keep yourself doing preparing to do something with the situation you can take the decision with no emotions, yet it will be much easier (as you’ll have been prepared already).

Just one small but important note, I think. When you dislike something at your work you usually load yourself with negative emotions. You should try to release yourself from those emotions and make your decision with “cold blood”.

No matter if you decide to fight for a change or to leave for a better place, you should leave the anger and the insult behind. Otherwise they will lead you to another mistake.
