I have the feeling that it is a bit more than chronic. I suspect that
it is more a matter of a denial of reality, that he is a lifelong
failure, primarily due to his own lack of effort.

One might even use the term "psychotic" liar.

I knew a man once that was a chronic liar. If it was a sunny day , he would say it was raining. I never understood him. It was not as if he was going to profit from saying it was raining. He was a nice guy. Did not put people down. Was friendly and courteous. But you just could not trust anything he said.
