I always had a hatred towards sales & marketing. As an engineering student I always visualised myself as the geeky developer sitting in a corner cubicle , releasing new softwares on daily basis. It never happened. Instead I fell in love with the then dark side of software engineering, which is also called as administration. After seven years I got enlightened. Life is all about "sales and marketing". Whether consciously or unconsciously everyone does Marketing and Sales.

Look back at your life. The day when you told your dad, "Papa,  see what I've made today". The day when you lifted your hand in the school when the teacher asked if anyone knows the answer. The day when you sat infront of the interview board. The day when you smiled at that person of opposite sex. The day when you completed the project before deadline . What were you thinking? Try playing all these down, but the fact is you-were-marketing. And whenever you were successful, treat that as a deal closed.
