Destination Infinity is the online identity of Rajesh Kollu, who is basically a 'Professional' Blogger living in Chennai, India. He has an opinion on everything and is an expert on nothing!
He was forced to become an author because people kept pestering him with the lethal question, 'What do you do?'.
When he answers, 'I am a professional blogger', people usually reply with sentences like, 'What is a professional blogger? I have never heard of this? Do you know anyone who is *also* a professional blogger? Will anyone in their senses become a professional blogger? You quit your *plum* sales career for this? Do you earn anything out of your work?', etc.
Now, since (at least) one of his books has been (self) published, he can safely say, 'I am an author, I write book(s)'. With that one sentence, he aims to eliminate any further questions, especially the 'Do you earn anything out of your work?'. Because, it's quite normal to be an author and not be earning anything at all!! :D
