For a bit there I was thinking you said spirit animal or "Digimon" like from,

this happens to me to often.
Think this idea has been around for a long time (I tend to see it happen in anime most often), the thought that everyone has there own form that represents them self (and not something you can pick for your self like some min maxing gamer) that ends up being out of this world is a pretty cool as well as interesting when you think about why you might be what you are or why other people are what they are.
I would like to hope that my own form would be some kind of bird haha, my love, interest and interaction with them has been with me as long as I can remember. So yeah it is kind of hard for me to hope which kind of bird I could be (that is if I am what I hope to be at all) even more so if you start to add in mythical/ legendary entity's.
I would offer things about me that I think could lead to what I might be most like but I tend to find/ think even if we know our self's well its only to a point, so I find the best way to know what I would be is to ask people around me/ know me well what they think are my good and bad points since there view should not be too biased which we our self end up being more then we might think. (even with the help of others it might not be 100% right but helpfully it is more accurate then what we might think of our self)
Haha I have had the idea in my head on and off for far too long so hopefully this is understandable.
P.S if I could pick I know I am 100% biased since I would like to be as wise, pretty and versatile/adaptive as a phoenix but if we are to take mythical/ legendary out of the picture a black swan is a bird I like a lot. 😊
