There were times where children used to say, "I want to become a doctor or engineer". There were also times where fathers used to be business men, doctors or farmers and mothers mostly used to be either home makers or teachers. But these are the times where a father is a business man, doctor, investor and what not! Also a mother is a home maker, business woman, tailor etc. With changing technology has come changing generations, to be more precise updated generations. My points below would explain in detail why a single career is boring and having several careers is interesting.
