Watch the line management video a few more times. Get the routine straight in your head. It will save you a lot of grief. Ignore the twists in the line as JB tells you in the video. They will pretty much all disappear when you put tension on the line. Regard everything in the videos as Gospel. It is tried and tested and will serve you well as you gain experience. You will eventually develop your own process, but for now do as instructed. It will help with not having to undo bad habits and will build muscle memory more quickly. I know you'll want to fly immediately, but equalize your lines first. If one of them is substantially longer or shorter the kite will be harder to control. Choose good wind to fly in for your first few attempts, ideally 5-10 mph with a standard sail. In bad wind you will learn nothing except how hard it is to fly in bad wind. Last of all, fly with someone who is experienced if possible. There are many quad pilots in the PNW since that is JB's stomping ground.
Have fun, smile and don't forget to breathe.
