My addres to the world

I am here, I am there, some say I am everywhere. I am high, I am low, I am near, I am far. I am the sky. I am a bird, I fly, the sky is my limit. I am a tree that never stops growing. Count my rings they never stop. I dont know where im going or what I will do all I know is that we are who? I am whoever I choose my self to be
