[Verse]
I was a feeble minded guy
I'd slip on ice and wonder why
So many obstacles were thrown my way
On a downward slide each and every day

[Pre-Chorus]
But something popped inside my brain
I got up to fight that fight again
And I knew what to do
I went through the mental pain

[Chorus]
You gotta think big, think deep
Pretty soon you'll make that quantum leap
Think big, think smart
Make your brain your finest body part

[Outro]
The greatest minds from yesterday
Will be crushed to dust 'cause I'm on my way
(Big, big, big)
You gotta think big!
