you've gotta want to.
i went out to PC this past winter and for 3 days straight i spent more than 70 percent of my time on the mountain hiking to ski fresh lines. granted, they weren't pillow lines in Alaska, i had the time of my life and on various occasions thought "damn this is what it's like to really ski powder"
and in terms of park progression, you've gotta want it. last two years i was satisfied with just sliding rails, 2ing out, and doing shifty's off jumps. got out there this year and learned 3's, learned 2's on, 4's off, switchups, and combos, and it's a hell of a lot of fun.
find some people like you. because when a lot of friends who aren't necessarily great at skiing get together, you'll naturally end up pushing eachother. you'll progress.
