Which one are you?
The first kind is the one we all know and love (or perhaps just tolerate through excessive eye rolls). This person is problem focused. They find a problem with anything and everything.
What’s worse is if you offer a potential solution they’ll probably find a problem with that too.
The second person is solution focused. They’ll complain as a way to vent their frustrations but then they’ll move on and do something about it.
The first person never manages to progress nearly as much as the second.
