I've only gone snowboarding once (a 2-week exclusively-snowboarding holiday), about 3 years ago.
It was a lot of fun, even though I didn't manage to come right too well.
The problem was that, even though I managed to get turning and such right, I really struggled to get much further than knowing the basics, as I'm too cautious about picking up speed (even carving was a problem, although the slopes were pretty steep, at least for me - it felt like about a 30-40° incline on most of the slopes where I was - this was on the "easy" slope - the "medium" slope seemed pretty similar).
I did fall a lot at first (as I guess most, if not all, new snowboarders do), so I can't imagine fear of falling, as such, is the problem.
I did take a few lessons during the first week. I got fairly comfortable with basically just going down the slope (at least better than with my board fully horizontally the whole way) and making the occasional turn, but the next part of the lessons was carving, which, as mentioned above, was a problem, so I felt a bit stuck for the remaining week and a half.
How do I get over this caution of going fast?
Choosing to ignore that little voice telling me to not go fast.
This probably wouldn't be too difficult, but I fear that, not being particularly experienced, I may not be able to react properly to certain situations (which may include trying to slow down / stop), and risk serious injury.
Picking up skateboarding so I can get more comfortable on a board.
Given that part of my problem is minimal access to slopes (because of distance and price), I thought it might be a good idea to get started with skateboarding, which I can do locally. A board's a board - right? Or not?
Just practice at the speed I'm comfortable with.
The problem here is the minimal access to slopes. And during my snowboarding experience, I seemed to just be stuck skill-wise during the last week of my trip because of this speed problem (not being able to go straight is a bit of a problem), so I'm not sure whether this will actually help.
I've also considered taking a really long snowboarding holiday (a month?) as to practice consecutively for a long period and hopefully get over my problem (although, if I don't, it might be a very depressing month).
Going to somewhere with slopes with less incline.
This should get me more comfortable on the board (allowing me to practice slowing down / stopping more safely), and hopefully this also makes me more comfortable at higher speeds.
Makes sense, but I wouldn't even know how to find such a place, beyond just going to different places until I find one.
Any advice on my problem or any of my considerations or any other suggestions?
Or am I too concerned about this, as it's just something that comes with time, and if it doesn't, snowboarding just isn't for me?
