Lyrics start at 0:30 and I Still need to fix up some stuff here and there.

I got Big dreams, small amount of money,
So many ideas, but no support for me,
I wake up feeling like it's still yesterday,
and i'm so tired of living off my loose change,

Idea's to blow up, probably wont make it there,
so i'm sitting in the shadows just waiting here,
for an oppurtunity for me to shine just once,
I know it's in the cards, i just need the chance,

Everyday I wake up in the same bed,
with the same aspirations in my head,
Plans for the future with no paths to follow,
but I'll keep chasing dreams till there's no tomorrow,

seems the people who don't deserve a single thing
are the same ones rollings around in everything
Nah I'm not jealous because i'm so rich in my life,
Have the greatest family and friends by my side

I just wanna do better, sick of being such a **** up,
try to make my family proud, so i'm aiming for the top,
One day i'll make it there, i'm just being honest,
and when I do, the first rounds on me thats what i promise

One day you'll see my name in the clouds,
No plans to stop till I make my family proud,
once i'm there, I wont stop, till i'm set for life,
3 kids, a big house and a gorgeous wife.

But for now;

I know i'm just young with so much to learn,
but i'm looking for oppurtunitys at every turn,
I wanna experience everything i can, yeah big and small,
so when i'm old i can tell my kids I did it all,
proud of me is what they'll be, i'll be the coolest dad,
kicking back in a fresh pair of addidas

No sleep, **** meals, long drives and flights,
thats where i wanna be, name up in lights,
providing kids with some music to kick-back too,
and nothing means as much to me as "thank-you"
glad I could help, give a thank you back,
fame changes people, well **** that,
Cus i'll be doing me till the end of my days,
even if the future right now is just a haze,

The future is the door, I've just gotta find the right key,
some people give up, well thats not like me,
because i'm like a used car, yeah i'm so driven
Wont stop till I make it yeah thats a given,

Got my last name in my skin, and thats forever
because my familys always right behind me, for worse or better,
and once I make it, I wont rest a single day,
i'll be doing what I love, something you'll probably never say,
but that's fine, you're sure to find happyness elsewhere,
it's what you deserve, I'm sure you'll find it somewhere,
till then never give up on your dreams, yeah you can make it,
don't listen to what they say, yeah **** the haters,
