About hundred of years ago, a man woke and got his newspaper from door. As he sat to read newspaper to his horror ans surprise he read his name in the obituary column. Newspaper reported the death of person himself by mistake. Firstly he got shocked but after sometime he regained his mental state to normal and now he wanted to find out about what people had said about him"Dynamite king died. he was merchant of death."That man was inventor of dynamite. After reading this obituary he asked him self, "Is this how I want to be remembered?"He felt something inside and decide that it's not way he wanted to be remembered and from that day onward he started working for peace. His name was alfred nobel and he is not remember for great nobel prize. The most prestigious peace prize given to people from different fields for their work towards peace. 
What ever we have done in past but still we can change our life and people views towards us. So never give up. Anytime is good to start good work.
