What if?

What the hell is the matter with the world? Why do we keep making the sames mistakes, the same wrong choices? Why do we put ourselves and the people we love in bad situations? Why do we risk our lives? But hell, why not? Sometimes I'm scared to risk too much, and sometimes I'm scared I'm not living my life completely. I know it's my own choice.. But what if I just make another wrong choice? Another mistake? What than?
