Keep at it
Basketball is a physically demanding sport, so it’s important to keep practicing and working on your overall fitness in order to become a better player. Practice dribbling while running, moving around obstacles, etc. Work on your dribbling with both hands (not just your dominant hand) so that you’ll have more flexibility during a game.
Because there is so much running required in basketball, you’ll want to work on your cardiovascular endurance as well. Practice sprints of varying distances to get used to the start-and-stop nature of playing a game.
You should also spend time practicing different shots so that you’ll be ready for any eventuality on the court. It may seem boring, but keep working on your jump shot, hook shot, layup, etc. Practice each one over and over and over again! You’ll gain the muscle strength and hand-eye coordination needed to make an impressive shot mid-game.
