I Know of Nothing!!!

I seriously study for psychology since I enter my secondary level. I try to understand people attitude and why do they take some act in certain situation.  At a level, I thought I found something and I understand well of everything.  I am really happy of that. Unfortunately, I still have doubt with the things that I learned and understand. Still got many questions that have no answers for me.  For truth, every people is unique and everyone of them have their own style and way of life.  It makes me realize that I am still know of nothing, nothing with no point.  What can I say, I  saw many things but with no real thing. I am still know of nothing.  Just keep moving forward by looking at every side that I can. Although I know of nothing, I am still continuing on my way of finding.  There are no gain if I am doing nothing too. Yeah, I must do of something in order to learn something!!! Nick.
