Preparation

Is being prepared, expecting something or preventing the unexpected? I have made conscious decisions not to be prepared and tackle the possible inciting incidents. Is this wrong? I wonder this, is every decision that I make affecting the rest of my existence. When I sets up to do something, am I deigning my fate or preventing fatal disasters. Dose every decision that is made have to be set in stone? I know my actions are unchangeable, because it is the past. My decisions are in the present and future and should I thoroughly think through everything or just roll with it. My direction in life has me going the opposite direction on a one way street. Should I change my direction in life if I have nothing to change it to?
