Just keep playing ball, bounce the ball all the way to school
Focus on feeling the ball on the way up, not so much power in your bounce but height is important. Try aim to keep it above your knee but below your belly button. Get lower to the ground, then progress higher until your comfortable
Do some drills, baseline to free throw and back, switch hands. Then try it again but with each bounce alternate hands.
Some nba players cup the ball on the sides and roll there hands over before they bounce, which IMO is lazy and cheating. Hands need to be on top of the ball.
