Let me guess, you're trying to learn on your own, thinking how hard could this be, I'm already great at other board sports ?
Do yourself a massive favor and book just a 2h private lesson to learn the correct basics and be safe for yourself and others.
You'll save yourself from a lot of headaches. Bad habits you develop from self-learning will take ages to break and will greatly slow your future progression down.
Australian ski slopes are where I've witnessed the most amount of out of control self-learners ever...each season forcing about a hand full of my instructor colleagues to fly back home from being hit and injured by them
Learn to control your speed by side-slipping, toe side and heel side. If you can't do that, no point trying to take the chairlift and going in a straight line...
Seriously get a lesson you won't regret it. Only very experienced and highly qualified instructors are handed the private lessons. Large group lessons are cheap but incredibly inefective and the main reason I stopped teaching this sport...
Equipment is the first thing an experienced instructor will look at before even starting the lesson, making sure everything is the right size and adjusted correctly
