simplifying life?

At those days, where the questions in my Religion Book were supposed to make a perfect muslim out of me, I began to create my own world! There is no God and the object of my life is simply living. In a way, reaching at the end while saying, I always took the right decisions with my knowledge at that time. Well! Of course there are limits, taken by each society I was or am living in, those which prevent me from making mistakes for their purposes.

And then there is my own life. I decided, I'll make two kinds of mistakes, those which I won't remember after 2 or 3 years or I'll laugh at them, and those which I'll regret my whole life. The first ones I forget right after realising. The others, well, I'm trying to keep them to a minimum. It was the best decision I ever took. But I'm discovering another type, which is troubling my perfect world. Those which I don't realise as mistakes!!!!
But wait, didn't I say my knowledge at that time!!! Why am I so contradictory!

Is life realy so simple?
