So how do you feel you ski?I think you are just thinking you'd like to improve to the level of others that appear to ski old school.
Make friends with the people as you get on the lift, since eventually an instructor might be able to help you, in many ways. They might point things out to yopu of skiers you observe on the ride up and occaissionally they will ski with you since they have free time, retired on a day off no students whatever. They'll offer you just what you need and no more. An actual lesson will overload your circuits(mine atleast) but that's me. I still know there is room for imrovement.
I suggest not trying too much. Skiing is a fluidic thing in a cold environment, naturally. Start the day figuring out everything and then let youself ski after that with a lot less thinking of the mechanics. i.e. ski ahead of you, with a desire to focus you attentions downhill, plan the turns so you can ski staight between them. Weight change can be thought of as pointing your toe in either direction and the ski can take it's intended radius, I think shaped skis turn on their own, almost..
After a while of thinking of your toes warm -up and ski thru lunch to avoid the crowds and thenlet them tell you it's last chair and cruise that last run right. v. varmit
