if you fail at a job, you could be in trouble for a while

If you fail at a job, you don't have a job. If you currently are happy about not having a job, then this shouldn't be so bad. Yeah, maybe someone will yell at you before firing you, but I simply reject that complaint. I can imagine months of stress when you believe you'll be fired, but I think that it is possible to accept a job as transitory and avoid this stress. I think that I would find this stressful mainly because the uncertainty of what I would do when the job is over. If I knew that I'd go home and play video games for a few months, I think I could avoid the stress. But, maybe I'm wrong; and maybe you're different. I'm probably more sympathetic to your other complaints.
