Factors of a good job

I realized today that there are multiple factors that determine whether or not a particular job is "good." They differ from person to person, and not all of them are obvious. From my two post under-grad jobs, I have gleaned information about my "good job" factors. From my time at Xilinx, I learned that I prefer a work environment that is low stress. I realize that all jobs will have deadlines, etc, but not everything needs to be reacted to in such a way that creates more stress for co-workers. Rational reactions will not result in unnecessary stress. I also realized I do not want to work in the IT/support environment.
From my current job, I have learned I require varying intellectual stimulation. Repetitive or monotonous jobs quickly lose my interest. I also need a mature work environment, where people are serious about their job, and the company they work for.
I left Xilinx because I did not like the unnecessary stress I detected from the employees we supported. I knew that the position at Peet's would be a much more relaxed work environment.
And now, in perfect 20/20 hindsight, as well as taking into account new knowledge about my preferred work environment, I realize that leaving Xilinx was a bad decision. Weighing the factors from both jobs, Xilinx fills more of them than Peet's retail does. Peet's corporate may very well be different, but I don't think commuting to Emeryville every day is a really practical thing to do.
So now, here I am, monotonously doing the same thing 5 days a week, working with young kids who don't really have much vested in the company. I on the otherhand, try to work by the rules I'm given by my superiors; but that seems to be an optional part of the job, given the behaviors of my co-workers. So back onto the job market I go, with new knowledge that will hopefully help me land a more satisfying position.
Update: Another factor that Peet's taught me is that I hate smelling like coffee all the time.
