Why is life like this?

Do you believe that our choices are decided by fate or that we create our choices ourselves as we go along? For instance if I wanted to climb a tree but my mum said I couldn't because it was too high and I denied her it wouldn't be denial, i'm just selective about the reality I want to accept. My dad says the world isn't fair but how come it's never unfair in my favour? Existence is not only temporary...it's pointless! What is life? Divine repuitational, that's what it is. You know when you are walking down the street on a rainy day and you look into a puddle and see a reflection of yourself? Well maybe the person in the puddle is real and you are just the reflection! It's that moment of dawning comprehension I live for. I am extremely sorry if I have confused you.
