Welll, I had my friend sorta teach me, but he had only been riding a year and told me to do exactly what you just said not to do. ...
Stop right there and take a lesson. One, maybe two is probably all you will need to feel 100% more comfortable and confident on the slopes, correct some bad habits, and start to develop good habits & correct technique & muscle memory.
I do ask some of the other riders for advice buuuut they're all dicks and just tell me to quit, say I'm trash, ect haha
Haters gonna hate. In all honesty though, most of them - although competent snowboarders - probably couldn't come close to *communicating* what you need to do the way Snowolf or another instructor could.
