for left hand just try and do everything left handed, write left handed, eat left handed do left handed layups, and dribble left handed. for dribbling just practice going fast and doing lots of moves. do that walk ( ithink its called the jordan walk) where u walk while putting the ball between ur legs and also when ur inside just dribble around the house with a tennis ball. if u can learn to juggle that helps a lot too.
