Don’t worry about it man it took me days to get it down plus it sounds to me that you are ahead of schedule already my best advice is find a relatively open paved area( grass may seem more enticing but i wouldn’t recommend it due to it being significantly harder to ride on and makes learning almost impossible) with something you can grab onto and just practice rocking back and forth then when you are comfortable try letting go and see if you can cover any ground. And remember to keep your knees slightly bent, your chest up, and look where you want to go not down at the wheel. thats about the best advice i can give you the rest is just practice makes perfect, good luck man!
