Like I said, there's an objective and a subjective here. I mainly found that people who are miserable at a job were miserable at every other job too. Doesn't totally mean it's "them" but it's kinda like "the only common in all your failed relationships is you."
Then there's the totally subjective. Example: two people get the same constructive feedback, one person goes "wow, I am getting feedback that will make me grow" and the other person goes "ouch my boss wounded my ego, I hate it". (I am not asking you to say one is good and one is bad, just making a clear example of situation that someone may like and another person may hate)
