180s are literally my favorite trick so hold my beer and let me explain.
Start by practicing some switch riding on the bunny hill just so you get the sense of control riding backwards
next take ur skis off and just do some 180's in your boots to get a feel, like the other dude said, it will help you visualize better too
Then, when ur on the lift, or just chilling, picture in your mind you doing a 180 and just play it over in your head like a little clip, this will help with commitment and fear mitigation
Find a small jump or a lip somewhere, probably hit it straight a couple time to get a feel of what kind of air time you have so you will know how fast to spin, so then roll off with a decent amount of speed but not too fast, turn your head and wind your body as you're going up the lip, then turn your body follow your head through the spin and keep your eyes around the horizon line, this will help when you learn 3's too so you dont get off axis.
hopefully that helps, you got this bro, definitely just keep in mind the commitment to it
