I need to make this rap better! can you just make a few changes to make it somewhat better... its for class.?

Self-made, been through what I've been through
You couldn't walk a mile in these 9  a halfs
Even if you had a chance
This isn't the life that we chose
But it's the life that we live
Some belong on top
Others could get there in a second
So its been a second
So I know what I know, write bomb rap songs
While your out there talkin' it, im in here feelin' it
Id let you get a glimpse of it
How im livin' it, Hi-Definition
Still young and getting my money
First class cruising at maximum altitude
Im tryna top that
So in touch with the real, they tryna stop that
Wake up on the other side, jet lagged
Ill be in the lead
So quick I can barely breathe
High enough, so I write my name on a cloud
Make everyone at home proud
Another day in the life
Another plane, another night
Then I'm up in the A.M.
Valet bringing my cars
A waiter to bring me plates
Pockets are always full, never nothing at stake
They say im livin to fast
But I don't plan on changing my pace
One foot on the gas
Never a need for brakes
12's in the back hit so hard Good luck trying to think
So far, so good
Cause I've been doing things that they wish they could
Everything from negative to positive
So its all good
