Can we talk. . . .

I am trying to learn the language of adults. I know that right now I am only learning speech patterns and rythms so right now the words don't mean that much to me (I know what your saying though. . . . I may be brilliant, we just have to wait and see) Anyhooo, My question is whether or not nicknames are a good thing. Names in general too, and what signifigance if any does your name/nickname have in your development as a person? I have about twenty or so at the moment.
1. Pinky (by Gwanny and Maimey [Amy] -- cause I was as little as a pinky when I was born) 2. Lil'bitty, Itty-Bitty or just Bitty (coined because my Daddy would sing Alan Jackson's Little Bitty to me when I'd cry, y'know "It's alright to be little bitty, from a little ol' town or a great big city")
3. Chicken or Chicken Hair (because it sticks up like a rooster's -- but rooster is not very girly)
4. Tinker, Stinker, Stinky, Tinky and Tinky Tinkerton (I occassionally have smelly diapers, and um. . . I'm a little gassy sometimes . . . ok, always -- I'm so embarrassed)
5. Piddy, Piggy, Porky (I apparrently eat like a little pig)
6. Barracuda (see #5 comment)
7. Any form or deformation of Lola that you can imagine and still stay rated-G.

And there are innumerable variations and short lived nicknames that I won't go into. My point (finally) is that how am I supposed to develop my own identity with 50 different names. And while I'm at it, how much does my name matter in my personality? The name books all say weird stuff about what names mean and how they contribute to the way other people view you etc etc. Don't deny it, any woman you meet named Bambi is immediately going into the "airhead" grouping and will find it very hard to escape that stereotype. So what is a girl supposed to do, can I lobby for a nickname that says something cool about who I want to be or is it all academic? Will I get labeled and stereotyped no matter what my name is? And if I fight to maintain my individuality will I be ridiculed and scorned or should I give up all hope of individuality and join the sheep and lemmings?
I like the idea of a single name. But I don't know which one I like best. Maybe two would be ok.
