It's enjoyable to think I am good and they are bad. That means I don't have to change anything, but in practice it won't help me to get next good-paying and mentally rewarding job. So, I prefer to think I am doing something wrong, or I have something in myself to improve and by doing that I take things under control.
And in the end, if there is something I can improve and I perform steps for the improvement, I have more hope I am getting better and valuable as a professional.
On the other hand, if I am good, and they are bad, what do I do? Find a `good` employer? What if I won't?
