Casting is something that takes practice, you can't learn it from a couple of movies (in my opinion) if possible, get some pointers first from an accomplished caster so you don't create bad habits. Where I fish is easy, it's mostly sand, nothing behind me, but, now and then I fish off a rocky shore, which for a novice like me can be a challenge, but an expert put me onto a washing baskets around my waist threaded on a belt, you pull the line into the basket, rather than at your feet in the rocks, you look like a goose, but it works great.
