The truth is, everyone was formed by their ancestors in some way. If you deny any connection to your ancestors, then that is a conscious decision which in itself, partially shapes who you are. Even by denying them, which is absolutely your right to do, and you may have extraordinarily good reasons for doing so, you have changed yourself in some way by making that decision. I have accepted this, and instead of being ignorant of the people that essentially made me, I have decided to try and find a connection to them via the myths and legends that they spawned; the tales they told and the beings they revered are part of their culture, and now they are part of mine. I heartily recommend to anyone to seek out something of what made you who you are today, perhaps something you have little knowledge on, or something you could feel closer to, and try and forge a bond with it; try and find a point where that means something to you as a modern individual; as a vibrant and unique human being. I discovered the Tuatha de Danaan. Who knows what you may find?
