well...with me...i just write like 2 lines..then spit them to make sure the flow will be good...then do it til i finish the verse...to make sure the flow is good...and it usually helps me memorize my shit too...when im done the verse...just spit the whole thing...and get focused..

BE the beat....SPEAK...what is on your mind my son:thumbup:...
which should be the lyrics..
