I ask because my mom is a 68 year old woman with a high school education in a rural community and she's had probably 6 jobs in the last two years. They aren't awesome paying jobs but at least half of them were full time and enough to squeak by. She just tries them on for size and quits them if they don't fit. Definitely a job hopper, but I don't understand how she can get so many jobs in a depressed area in the midwest and folks like yourself remain unemployed.
Well, self-fulfilling prophecy: now I'm following my more heartfelt interests and doing a PhD in neuroscience. Turns out finding a lab that fit my interests perfectly worked great.
Which is to say: being the "spiky fit" actually sucks, but it seems to be what the labor market is targeting right now.
