[Chorus: Wiley]
Don't do it if your heart ain't in it
Don't try and do it if your heart ain't in it
Don't be a bad boy if your heart ain't in it
Don't come against me if your heart ain't in it
Don't do it if your heart ain't in it
Don't try and do it if your heart ain't in it
Don't be a bad boy if your heart ain't in it
Don't come against me if your heart ain't in it

[Verse 1: Wiley]
Don't do it if your heart ain't in it
I do it, because I'm in it to win it
I've got lyrics
I'll be in the game til the whole game's finished
Some of yous give up because your heart ain't in it
I knew one bredda when his heart weren't in it
He saw the limelight and he thought he'd seen it
Now he's washed up, on the sideline, shotting B
Even if he came back, I’m afraid he can’t win it
Since that day
That soundboy left a level of MCs that changes every minute
All the bullshit blud, I ain't in it
I make my flows stink like fern in acrylic
Hear my music, yeah my heart's in it
And when I write my bars, my heart's in it
Catch me on the road with real street people
Ready to get busy, believe my heart's in it
Even if I gotta live to see another day
I'll be back to show you that my heart's in it
If there's a spider in my room, I won't kill it
But humans, they try push it
I'm the meaning of raw, look it up
I saw the title, I came and took it
You want some of my time, then book it
Don't beat around the bush, and don't play crooked
A lot of them rap it, but they can't hack it
They know what money is, but they don't stack it
Is that a two two, or a baby niner you're packing?
My advice is saying that you're lacking
I don't know what you take me for
Like I don't know about gun clapping and human trapping
I've been a don since back in the day when them man was fussing
Eskiboy
[Chorus: Wiley]
Don't do it if your heart ain't in it
Don't try and do it if your heart ain't in it
Don't be a bad boy if your heart ain't in it
Don't come against me if your heart ain't in it
Don't do it if your heart ain't in it
Don't try and do it if your heart ain't in it
Don't be a bad boy if your heart ain't in it
Don't come against me if your heart ain't in it

[Verse 2: Jme]
Don't do it if your heart ain't in it
You must've been, but
You don't have to do anything you don't wanna do
Unless you give yourself a reason to
If not, then your heart ain't in it
And you end up half-hearted or quarter-hearted
You didn't really start, you sort of started
But you didn't really give a clue
No point starting with no heart
Stop thinking the start if that's the main part
You won't get far with no heart
Until the point you wanna rewind back to the start
This ain't a CD, there's no back skip
This is life blud, you'll get a fat lip
So think twice blud, because it's drastic
If your heart ain't in it, you're wasted
You're a wasteman, you're empty
My heart's prominent here, not temporary
My heart's in this, I'm still heartless
I'm still serious, so don't tempt me
You need a heart to have a good performance
My heart's active, your heart lays dormant
So don't do it if you heart ain't in it
Or you might as well go stand in the audience
If you're half-hearted, you might as well quit
You're making it harder for the rest of us guys
Out trying to spit
While you're half-hearted, chatting shit
Don't mean to put you off, because that's wrong
If your heart's in it, then carry on
Catch the meaning of the song
Half-hearted is long
Serious
[Chorus: Wiley]
Don't do it if your heart ain't in it
Don't try and do it if your heart ain't in it
Don't be a bad boy if your heart ain't in it
Don't come against me if your heart ain't in it
Don't do it if your heart ain't in it
Don't try and do it if your heart ain't in it
Don't be a bad boy if your heart ain't in it
Don't come against me if your heart ain't in it
