Boa tightened boots suck. Like they are good if you're not strong enough to tie your own boots, great for people just getting into the sport. But they just don't stay tight through the day. I also don't think they last if you put more than 25 days in a season.
Ice coast wisdom: Ski it till it's good. Don't let conditions get in the way of having fun on the mountain.
I've taught snowboarding for like 12 years? The best advice it to get an understanding your fear. At some point along the line, my fear response has turned into an adrenaline response. So when I learned how to mountain bike this year, after a couple of falls I really started to make progress. The more fear becomes excitement, the faster you're going to learn. That being said, you want your fear to meet up with the actual danger of the situation, not exceed it, that's how you die in an avalanche. Confidence also fits in there too.
When I was training instructors last year, the clinic that seemed to help them out the most was when I filmed them riding. Get a friend to take videos of you, you'll try your hardest, and you'll be able to see where you need improvement (if you're following along with YouTube tutorials.)
Yeah, I get you on the tiny mountains, been snowboarding in buffalo region. Pro tip to annoy your friends from buffalo, tell them it's the Midwest.
I still believe fear is a major blocker for people to improve. Snowboarding is a sport that benefits from being relaxed and in control, being tense instead of loose makes progress much slower. Finding out how you can build your confidence is where to start. How scary are falls? Wear knee pads so you have a safe thing to fall on, and to save your knees(I'm a big fan of knee pads, I recommend g-form.) Learn how to slide and roll out of falls, I hurt myself less on the super steep trails because when I fall I slide instead of bounce off the ground.
Lots of beginners are afraid of their toe edge, this is because usually they try to balance on their toes. We shouldn't be relying on our calf muscles for that, since they are fast and twitchy. Instead, if we let our shins rest against the tongue of the boot, our slow strong thigh muscles are much easier to balance with.
Get a lesson. Youtube videos are amazing, I learn things from them all the time. But having someone good watch you ride can solve so many issues because they can see stuff your eyes can't.
Lastly, workout. Get in shape. You will be less likely to hurt yourself falling or getting up. You will also be able to preform snowboarding skills much easier with a well-developed body and will have a better understanding of how to feel your body position and move your body.
