You'll get it! Try to find a longish slightly sloping downhill to practice your riding balance and turns. Something where you don't have to peddle much or at all to still go, but not too steep where you're picking up too much speed to feel comfortable with.

To practice peddling you can just try to balance on your front foot, on your board, for a bit while you're stationary. If that's too hard you can put the board on some dry grass or something so it doesn't move. If it's pretty easy try moving your push foot like your peddling. You can try moving around in random ways too while trying to keep your balance. The better you can balance on your front foot in general the easier time you'll have pushing.

If youre ever just standing around somewhere try balancing on your front foot for as long as you can. I'm literally doing it while typing this.

You can tell how comfortable someone is on a board just by how long they can go between pushes while not having to go back to two feet for balance. Does thst make sense?

There's probably better advice/tricks online, I'm all self taught and only good at the actual riding part. It was mostly on long boards too, but I bombed down big hills in a crowded city so I'm pretty comfortable on any kind of board.

Also try experimenting with loosening or tightening your trucks. Too tight makes it hard to turn, too lose and you're gonna lose your balance.

Also never ride in the rain and try your best to avoid going over any kind of puddle. It'll fuck up your bearings and there's nothing worse than shitty bearings.

Have fun!
