Today i got rejected by a Delhi-based company in a telephonic interview. I feel really dejected and crestfallen. I had failed once again. I don't want to end up as a loser. I am a nice person , why does bad things happen to me. I want to change my life, god please help me change my life. I don't want to end up living a miserable life. God please help me.
