There are people out there who don’t think they have a thing to offer this world. They assume they have no talent, skills, or reason for showing up in this creative game of life. Then there is this other group at the opposite end of the spectrum who have a cognitive bias called Dunning Kruger effect.
They assume they can do just about anything better than the skill set they currently possess. You may think this sort of psycho is annoying. But I think having this bias is great asset to creative work.
