you oughtta get some instrumentals on ur computer to rhyme to. helps to keep it organized ya know.
here's one to big poppa by biggie.

whether it's crispy or it's soft
i'm a bout let it off,
start it off slow, but
Lo behold!
I blast off.
Ima Master,
Campactor,
of the words ya heard
Me slur that u were
quickly running after.
Manufacture fiends that
that u'd of hafta seen,
to believe me cuz
I deliver em dreams.
once was an icon,
once,
once was on top of his game
but bit the dust.
One must
persevere to maintain
these days things just
never stay the same
in this paid game.
if u wanna do it big,
then say it loud
rattle rhymes offa ya chest
in front of crowds.
u gotta amount
to something more
than the miniscule
ridiculed hopes ur rappin for.
don't get that wrong:
keep ya dreams,
just keep in mind couple
of these things.
even when the pot seems hot,
starts to simmer,
the cookin seems done and
ya ready for a dinner,
don't provoke ya hopes
cause in a minute they'll turn
to steam and be out like smoke.
but if ya never choke
hold tight, if ya position's steady then
get ready u just might
reach the limelight.
rhyme tight, n stick ur slurs
n that's my advice now
let me your urs.
