“You better lose yourself in the music, the moment. You own it, you better never let it go. You only get one shot, do not lose your chance to blow. This opportunity comes once in a lifetime, yo.”

That’s Eminem quoted in the first chapter of Make It Happen: The Hip-Hop Generation Guide to Success (Atria, 2005), by Kevin Liles, former president of Def Jam, current executive VP at Warner Music.
