This is a topic about self delusion.

Have you ever somehow been convinced that you were good at something even though you weren't? And people would constantly say straight to you that you weren't good, yet stubbornly enough you continued only to make yourself look even worse? Persistently, over and over again, even after you'd been forbidden to do said thing?

I don't think I have, personally! I'd hate to think I'd be that much of a jerk
