I feel like I need to say something about that.

Its partly true. Most of the time it is a systematic problem in bigger companies. Those are fact driven. So just running around ranting will mark you as the problem, even if you’re not really.

There are strategies how to sort feelings and thoughts, before going off. Thats something I learned in my career. Venting is important - but in a certain extend.

One thought that I have about colleagues that are pessimistic is: Be part of the solution, not the problem. Often easier said than done. But there is a lot of truth behind it.
