Are entrepreneurs born or made?

There are 2 schools of thought: Any woman can start and run a successful profitable business if she really wants provided she put in the effort VERSUS she has to have a certain entrepreneurial, operational and managerial DNA otherwise she is wasting her time. Therefore should women be encouraged to start businesses, or should women demonstrate specific skills, abilities and knowledge before being encouraged to start a business?

NB: I haven't calculated my score, there are no questions slanted towards starting a business three weeks after moving to a foreign country, with little capital and no real business plan. I'm in the anyone can do it camp. Some of the skills required would make the most battle hardened corporate queens crumble and no business plan can take account of the inevitable evolutionary cycles that occur so sticking to hard and fast rules can mean all that booklearnin' can just get in the way.
