I don't know where you read that but I think they must mean serial entrepreneur. Depending on the context it might have been a form of wordplay. Headline writers in newspapers like to make jokes like that sometimes, so they might call someone who invented a new breakfast food or started a chain of coffee shops that open very early in the morning a "cereal entrepreneur" as a pun.
A serial entrepreneur as you probably know is someone who starts a string of companies one after another. Usually they enjoy being part of a startup and once a business gets mature they're happy to sell it on to others and go look for the next idea.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
