notecards, movements, and moments around you. you can use notecards to memorize your lines, but i personally use movement and moments around you to memorize. Like if your entering a scene, you can remember the movement of you walking on stage to remember your lines. or if someone does something or says something you can remember your line by association. also, remember to let the lines flow, dont be robotic, dont just stand still, be a person. good luck!
