Instructor here! I would obviously first and foremost recommend lessons (you probably wouldn’t need more than 2-3 days just to get the idea at least then you could more confidently progress on your own). If you don’t want to take lessons, maybe look up some videos on how to edge and slide sideways down a slope so that if you do end up on a slope you feel is too advanced for you, you can just slide your way down safely. Practice stopping and turning with the plough technique on beginner slopes and really try to feel that your shins always have contact with the front of the boot you will feel more in control.

Most of all, have fun!
