And confidence has no budget
So pay me no mind

from Lil Wayne – Dr. Carter Lyrics on Rap Genius

Meaning

Shit! Where is this Lil' Wayne?

Basically, by Weezy increasing his vocab in taking away his pain(Vicodin), Weezy has directly increased his confidence but he doesn’t want anything in return so he says never mind (“…pay me no mind”).
These bars are genius.
