A bad tradition is using grandpa's old gun starting out..
Welcome to the forum... I am not into recommending any kind of special rituals except to please use a rifle that fits your body. You will find range time critical to enjoying the sport. Range time will not be fun with a rifle that doesn't fit you. There are no shortage of us that will make suggestions if you currently don't have your own dedicated rifle to shoot. I can't get my wife to be interesting in Deer hunting. If she was I guarantee that she would have a perfect fit before she ever pulled the trigger at the gun range. Having fun is the most important part of shooting/hunting.
