About me

Hi, This is Arjun. I've always prided myself on doing things on my own, strenght in my solitude, adopting a man against the world attitude. Many do the same. We have all heard that life is a joureny, be its spiritual, emotional or just living our lives. If this is true, then all the lives one has touched and of those that have touched onces of weill always be with you. so when walking the dark road thinking no one is by your side, one is never truly alone. Remember, no one has a choice in the start of their own life but one must bravely walk to its end.
