I love this definition of entrepreneurship by Ken Morse, previously the head of the Center for Entrepreneurship at MIT. This article from MassHighTech…
Morse: My definition of entrepreneurship is the same as Howard Stevenson’s. That is, pursuing a project without having the resources needed to finish it. Starting before you have everything you need to get it done.
Sagan: It sounds a little bit like the definition of insanity.
Morse: Yes, but it also means that in large corporations you go to meetings where you have great ideas and the first thing you hear is some genius from finance saying, “Well, we don’t have a budget for that. We’ll have to wait until the next budget cycle.” That, of course, immediately puts you at a strategic, competitive disadvantage.
