I'm quite similar to the OP.
I "learned" to ski (self-taught) as a teenager on ski hills in WI. I saved up to buy my own skis and went as often as I could. I took a few trips out west (Beaver Creek and Heavenly) in my late teens and early twenties but due to school, funds, and time constraints didn't ski all that much.
Fast foward to my 40th year. We move to northern Idaho. A short drive from Schweitzer. YEAH! Holy cow, skis aren't straight sticks anymore! What are those fat things? Lol.
I've still never had a professional lesson (planning on it, but getting my 4 kids all outfitted and in lessons consumed the budget) and am trying to learn what I can from youtube and talking to my kids' instructors. (And yes, I do slow down and eavesdrop when I happen to pass someone having a private lesson.) I try to challenge myself every week to focus on one aspect of my form or to tackle a new type of terrain.
I do hope to ski as long as possible. I was not kind to my body for a number of years. Marathon runner, not eating enough, etc. I'm working on rebuilding and strengthening so I'll keep going for a long time.
And I'm hoping to learn a lot here. I enjoy all the ski chatter.
