Everybody's got something they're striving for (Yeah)
It's not a game, it's real life and I'm here to tell you
You can do better than what you're doing with your life (Yeah)
But you got to believe, got to believe
I swear, I swear, I swear (Oh)
Yo, I ain't tryna brag or nothing like that (Yeah)
But if you're looking for motivation (Yeah)
You know I'm here to help you out (Yeah)
And if you need a little inspiration (Yeah)
You know what it is, yeah, it's real life and it ain't a dream come true

You might get some laughs from people on your way up and they say "Huh? But we all go through trials and tribulations yeah"
Now when the music hits, put your hands up and give love 'cause now we about to blow yeah! (Oh)

You don't have to sacrifice what you really want to be to impress somebody else oh no no no oh! (Yeah)
It's okay to be you and it's okay to want the top oh no no no oh! (Yeah)
It ain't about what they say about you or what they see oh no no no oh! (Yeah)
Just believe in yourself and go for it girl oh yeah! (Oh) (Oh) Yeah! Yeah! (Oh) (Oh) Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh! (Oh)
