just think on a subject...and try not to concentrate on anything else...I been doing topicalz so long that I can just keystyle all mine up...if you look at any of my open micz...100% of them are off the dome...but you get better with experience...just concentrate...it's a whole shitload easier if you make it about some thingz that you have actually experienced...but once you get the hang of it you can write about just about any topic given...just practice on what I told you and ya should be dope in no time...holla if ya need anything else...sn'z in profile...
