Gotta know the game, gotta know the lane
Gotta know the pain,

from A$AP MOB (Ft. ASAP Ant, A$AP Rocky & Flatbush Zombies) – Bath Salt Lyrics on Rap Genius

Meaning

Gotta know the game; Juice is telling us how to survive when you a part of the trap game:

Gotta know the lane — know your place and your path, if you get outta lane, your ass getting stuck up or killed

Gotta know the pain — you have to understand the type of struggle, pain and pressure put on by the crack game, you have to fight through it, or ya ass going under.

..ain’t shit easy
