If you do what you always done
Then you get what you always got
You dumb buffoons!

from Kendrick Lamar (Ft. Gunplay) – Cartoon & Cereal Lyrics on Rap Genius

Meaning

Continuing from the previous lines, Gunplay again preaches not to keep doing the same daily shit over and over because you won’t feel anything new ever in your life if you repeat the same shit over and over.

It seems as if Gunplay is channeling his inner Einstein:

Insanity is doing the same thing over and over again, but expecting different results.

Keep on selling drugs to get that quick cash and you’ll stay stuck in the system and going to jail, to be more specific. .
