Entrepreneurship is all the rage. It’s everywhere. In TV and movies (Shark Tank, Silcon Valley, The Social Network), in books (The Four Hour Workweek, The $100 Startup, Lean Startup), in podcasts (StartUp, The Smart Passive Income podcast), and of course in blogs (Techcrunch and countless others). Entrepreneurship has gone mainstream. There are at least 400 startup incubators and accelerator programs in existence.
