Keep riding. Do plenty of shit you're comfortable with. If you can hit a 20 foot jump decent, hit it until you can do it in your sleep. If you've 3'd a fee times do it until it's locked down get a good grab and style.
It's all muscle memory and that builds confidence snd style. You know how fast you need to go, what the jump or trick will feel like. If you're crushing 3s try the occasional 5 etc. Especially if you already have a jump dialed in.
Sometimes if you're having a slow start, hit one of the easier parks that doesn't scare you at all and throw some of your best tricks on small features. It will get the legs to start cooperating and get your brain to think "this skiing thing,im not bad at it".
For bigger jumps, jump lines are aleays good. Maybe jump line goes 25',32',40' but you only have hit 30s. Take the jump line as far as you feel comfortable. Maybe you skip the biggest hit in the line. Then one run you land 1 and 2 pergect3and just send 3. Everything feels good landing is clean and stoke level 1million.
Also following a friend in for speed can be good. If you know the speed will be right it's a little easier.
Just dial in tricks on smaller jumps and rails then work your way up. Keep hitting some bigger(for you) features even if just straight airs and basic slides. When you get comfy af with said trick and comfty with bigger features, put them together and go pro. Now you're the best skier on the mtn.
