If you can watch a video and then lay down the trick, go for it. I'm not sure if it's really worth it though. The best way to get better and progress is by just skiing, if you're struggling with a trick, you can always ask a fellow skier, most are happy to give a few pointers if they aren't lapping or filming. The stuff you get from people on the hill is as helpful if not more helpful than lessons.
You can even learn for free off of newschoolers with the trick tip forum, there are countless threads of people looking for advice on tricks. Just search that and you'll find what you're looking for.

If that fails, just PM me a video of you struggling with a trick and I can probably tell you what you need to do. But most importantly just keep skiing and trying. You'll get better with time, there's no race to get better. Ability comes from how much you ski and your willingness to try new things, not by how many tricks you can do. Have fun out there.
