I abruptly quit only one job in my life. I was 22, it was the middle of the day, and I just went into my boss’s office and quit. Something had happened that just exceeded my tolerance level, and I couldn’t take it anymore. I was unemployed for six months after that, and I’ve never done it again. But if I had it to do over, I would. Sometimes what you give up in a job is bigger than what you get from it.
