Nailed it.
I was going to say "...a sharp knife", but scissors will do.
either buy a practice plug, or take the hooks off a lure and practice around the yard...even in the house (I practice pitching inside off and on all winter.)
I have a drill I do for my fly casting, every night the weather is decent: I cast my my way around the house. At least one rod, and often two or three in different weights. This makes me deal with the wind from every direction, trees, shrubs, whatever I can make get in my way. I cast under branches, around bushes (you can do that with a fly rod, to a point) and right next to branches where I imagine a monster pike lurking next to that gopher mound...
Shoot for targets, don't just go for distance, as accuracy is 10x more more important. Tighten up your "short game" with pitching, and learn flipping. Plastic buckets, hula hoops, weeds, darker/lighter spots on the lawn, gopher mounds, leaves in in fall, and around here the occasional Brittany* have all served as targets at one time or another.
