make sure u know ur lyrics off to of ur head... move around the stage as much as u can, dont look to the floor, try making eye contact with the crowed(it helps with u looking confident) dont jus t shout ur lyrics.. alot of rappers make that mistake, yes, put some more energy into it... but not that much more because u still need to keep ur delivery rather much the same to help the ppl feel wat ur sayin.... but the most important thing, have fun
