a piece of something

Everyone has ever thought about life. When I try to decide what I really want to do in the future, in most cases, I have completely different ideas. Sometimes my thoughts are connected with my field of study, sometimes with science, but how can I make a decision? It is always so hard to choose.
I am a 20-year-old foolish girl with irritating but funny behaviour. I am too young to think about my future! :)

We use :) to denote a smiling face, in Russia it is ))...using ) in English looks weird and like a mistake.

Not sure if you are learning American or British English but, in America we spell it Behavior =]
