This is a great song because it's so self-aware. It's about being on a road to self-immolation, knowing it, and telling the world "fuck that/Imma do just what I want". The first few lines are about boozing - "Drivin' drunk, I'm doin' my thing" - and smoking crack - "Crush a bit, little bit, roll it up, take a hit" on a summer's night. The singer knows this lifestyle will result in him burning out too fast, "People told me slow my roll", but he doesn't care about the "trials of tomorrow". At the heart of it is the emptiness the singer feels - the "pursuit of happiness" and the irony that "once I get it, I'll be good" - but this drug-induced "happiness" will only last until "5 a.m, cold sweats wakin' up, to the sky" when the withdrawal symptoms kick in, and over-indulgence is self-desctructive, "Oh my god why did I drink so much and slug so much? Ah/Ugh, fuck". Short term thrills allow him to escape the reality that "everything that shines ain't always gonna be gold", the decadence of his world which he knows is futile and not true happiness but isn't he "Livin' my life, getting' out dreams", "lived life to the fullest"? Awesome song - conflicted and angry, at the world and bitterly ironic towards himself.
