If you're a bass fisherman, don't you dare catch a fish on your first cast. Tradition has it that you'll have lousy success the rest of the day. That's why I usually flip my first cast out near the boat where no bass could possibly be lurking and retrieve it quickly before a fish finds it.
If you're a hunter, there are many more traditions we deal with every hunting season. Of course, you remember what happened when you got your first deer. You were probably a little squirt and were proud to wear the badge of a successful hunter; you got blood from your deer liberally smeared over your face.
