Also a pun on the samurai saying: live and die by the sword.
and his next album is gonna be called ecology too.
He doesnt want to smoke it cause he doesnt wanna be nervouse all the time, he’d rather live somewhere calm.
It fits his career to, he is expressing his liberty through out this song and album and it’s gonna be done properly can be explained that he releases several mixtapes before his albums. He is not going to force it, acualy it’s 4 years ago he released his only album up to date.
Everything he thought to be true was a lie could be that he thought she love him but itwas a lie since he says earlier the verse that she had learn to fake smile.
Ironicly in the hook some days I dont even wanna wake up.
He is responding to the line http://rapgenius.com/2092508/Big-sean-control/Im-makavelis-offspring-im-the-king-of-new-york-king-of-the-coast-one-hand-i-juggle-them-both saying that Kendrick isnt king of New york or of the west coast since the west coast has Snoop Dogg and Dr Dre and New York has Nas and Jay Z
It’s also a double entendre of falling through a crack in something and falling for crack the drug that alot of people gets addicted to.
By being real? he has acted like a thug in plenty songs.
I think he is saying that he hasnt time for material stuff like watches, because like chains that he mentioned previously is something alot of people( whether its rapper, gangsta, new slave etc) buy to look cool not because they need to know what time it is.
