stay on one’s grind
v. phr.— «One of the most important jewels that Juelz has picked up is to stay on your grind—or as he calls it, “G-rind.” He didn’t wait for Def Jam or the Dips to fund videos for the singles that set up the album, like “Mic Check” and “Shottas”—he funded the clips himself.» —“Juelz Santana’s Hard-Hitting Game Makes Cam’ron, His Mentor, Proud” by Shaheem Reid MTV.com Nov. 22, 2005.
