Spending time with a more experienced archer can get you off on the right foot. Ask questions and watch him when he is setting up his bow or maybe he will help you set up your bow. Hands on experience will help you learn faster and you can ask questions on why and how as he is helping. You're going to make some mistakes, everyone does, but once you see it done your confidence will grow and so will your skills. One very important thing to remember is to keep a log on your bow. Such things as brace height, top, bottom and center. Rest location, nock set height, peep or kisser location and cam placement. Than if something goes bad or you change cable or string, you will have a reference to set your bow with out hours of trial and error.
Good Hunting...
