Get in touch with your local community, its a really helpful tool and should accelerate your learning. If you haven't got one, get a password from the Parelli office, then you can get onto your community webpage.
You will probably fumble aroung with the rope, the carrot stick and everything at first, i know i did, but they soon become part of you! (and i'm only 5ft2!)
Don't try to be too much like Pat, the problem with the Level 1 video is that he uses a Level 3 horse and you try to be like how its on the video and it just doesn't happen! The best tip i was given was that Level 1 doesn't have to be perfect, you pefect it all in Level 2. So don't spend too long on L1, get it video'd and post it off. If you can get on a course too, that really speeds it all up!
Good luck, update us how you do / find it all.
