You don't need to be an academy trust fund baby to be however good at skiing that you would like to be. You need to be methodical about it if you want to get good and stay healthy. Start focusing on eating well, exercise and stretch regularly. Listen to your body when it needs rest and when you can push yourself. Everytime you go skiing, have a list of tricks you can do but need to work on dialing in. Do "X" of each in a satisfactory manner. Then make yourself learn 1-2 new tricks everytime you go out. Identify your incompetentcies and force yourself to work on them. Example, I can't look over my left shoulder skiing switch. That limits me from switch left spins and forces me into a certain approach. Make sure you work on jumps and rails. Have homies film you and be critical of your technique. Focus on doing things WELL.... Not just landing it. Proper technique and getting these things down will help prevent injury, increase your style and be a stepping stone for you to get really good. A lot of this is tedious shit that not many do, but not many are really good at skiing either.
You just need to be motivated, hungry and love skiing. Tons of dudes think they love skiing until they get the chance to do it everyday for awhile and realize they really like skiing but they don't love skiing.
