If the Dunning-Kruger Effect says dumb people think they’re smart, does that mean I can make myself intelligent by thinking of myself as an idiotic failure?

I don't want to be stupid and dumb, I want to be smart, but if I acknowledge my smart moments in life, I worry that I will become dumb because I'm thinking too highly of my intelligence, so what if I just call myself a stupid fucking idiotic failure everyday? Would that make me smarter because Dunning-Kruger Effect says dumb people overestimate themselves while smart people underestimate themselves?
