I have also struggled to hold a job. I have had 9 jobs in 5 years. I partially blame this on getting the idea that I should switch career paths, and partially on getting bored of being at the job. It is normally when I am manic I decide that I no longer want to do this. I have worked in food, sales, nursing, and information technology. I have had 5 or 6 different majors that I never finished.
