"Nothing in life is to be feared; it is only to be understood."
In this life we going to face many situation.. its make us happy, but sometimes makes us sad.. not to forget makes us angry.. there so many things can happens in our live..no matter how much we try to avoid it.. we still have to face it.. people says that live is short.. but the truth is live is so so so long.. and should adapt it smartly.. Thats what its mean by understanding it. Don't let the situation control us.. but control them and your live should be on your own course... :)
