During my 13 years of existence, I've come to the understanding that  no one is to blame for your own actions and mistakes. You are the only person held responsible and only you can use failure as a stepping stone leading to the pathway of success. Challenges can come your way but it's your sole duty to use the challenges to your own advantage. Just think of these challenges as "storms that clear the path that ultimately leads to success ." Sometimes you have search for the positive aspects in things by changing your point of view and not look at life through through rose-coloured glasses nor turning a blind eye to the reality of the World by just assuming that everything is just simply black and white. Occasionally, life tends to be really misty but you should just wait until the right moment when the mist disappears and everything becomes visible once again. So, I guess my real message to you guys is that you should stay hopeful  as well as optimistic at all times and never ever let your guard down at any given time and to always stand your ground.
