I found this to some use myself on lif.com

take the topic... and think for a minute, all the things that
relate to it... expand your mind a bit...
in other words... BREAK IT DOWN

say the topic is: your brother was stabbed and you caught the bastard that did it.

-start off with how you found out that your bro was stabbed...
-put your reaction into the verse... add in your first thoughts...
-what would you do when you found the stabber...
-what you actually did...
- how shit progressed...
- anything else...

just break the shit down... but make sure to maintain that killer
flow dawg.
