People who pretend to think that you can simply willfully infuse yourself with positivity annoy me.
Negativity is how individuals react to certain environments. You can change some features in the environment and fix that, but simply demanding everyone to be positive is stupid. It's essentially a demand for suffering in silence.
I was working data-validation at a big tech company, and the data-validation tool was under active development. It'd crash ~20 times in an 8 hour workday. I would happily restart my Tool and get back into it, but other people would huff and puff and rant. And it's like: What are you accomplishing with this attitude?
Empathically speaking, maybe it's because they have a hard home life or had a tough childhood. But it's unprofessional and your negative energy affects me. So I'll be the mirror you need and throw it all back in your face. :)
You're communicating to others that you don't consider an app that crashes 20 times a day an acceptable norm. The question is, does anyone listen?
Sure, there are things that are unchangeable and there is no point in complaining about them. But if you have a positive attitude towards cockroaches in your food (figuratively speaking), it's no longer positivity. It's called not giving a fuck.
Yep, most people most of the time get those as a reaction to their environment, but they are not caused by the environment, positivity and negativity are always self inflicted.
Anyway, I don't think a positive attitude is always the best for a person, but most of the times, it is.
We're not talking about using positive thinking to imagine everything is hunky dory. The issue is strong negative emotions. If you are constantly having strong feelings of anger which you are repressing, that can lead to burnout.
Usually there are better ways of dealing with problems than getting silently angry.
