I meet sometimes people that are self-sufficient.
There’s nothing wrong with being happy at the place you currently are in your career, personal life, or other parts that make you a person.
But to constantly say, „it’s OK where I am”, to answer „I don’t have any issues” to any kind of feedback might be a way to just refuse to grow.
„It’s never like that!” Perhaps, you’re right. Still, give it a try. See how that image fits your personality.
On another hand, you should also be able to stay „Stop, I have enough, I don’t need to fight anymore, I can settle with the current level”.
