A happy person with reachable dreams will answer that life is a gift, a miracle and it's worth to live and enjoy every moment of it , no matter what.

I'm neutral. My life is not perfect but it doesn't mean I'm not gratefull for the things I already have. Besides, if something is wrong, you can always try hard and correct it.
