I am thinking long term work situations here....
One is doing stuff I love, but not much of a chance of ever advancing, and not a lot of job security (contract work, so more like 'if' there's work). Pay is ok but it gets frustrating with not having any say in things - it's a show up, do the work, go home sort of thing.
Or do something I don't really like as much, that has more security and chances to advance. Not sure what that would be yet - might go back to school, who knows...
